link to mustang gas tank install
 

Did a search but couldnt find it. I remember seeing a thread about installing a 65-68 mustang gas tank in a 55-57 red primered big window pickup. If i remember right installation in thread wasnt completed because truck was sold. Anyone have the link?

Re: link to mustang gas tank install
 

Here are some pics hope this helps some are from the hamb and the other on the web. What I did was drill ribits out of rear crossmember and flipped opposite way and moved toward the end of frame stock holes all lined up so it was an easy bolt in.

Re: link to mustang gas tank install
 

What is are you using for a sending unit? I want to use the stock fuel gage.

Re: link to mustang gas tank install
 

Made a round metal ring and welded to top of tank added a little JB Weld epoxy around ring where I welded it for cheap insurance for leaks. I tapped the ring for stock sending unit. All I had to do was cut down a new stock sending unit replacement for depth of tank. :ito:

Re: link to mustang gas tank install
 

I realize nobody has posted on this thread in a while, but I've been reading the forums all week, & looking to do this on my '58 Chevy stepside.
I have alot questions.

1. When relocating the rear crossmember, does it weaken the support for the stock leaf springs
2. What filler neck can be used for rear fill, & flip down license plate bracket
3 What size channel is used at the rear of the tank for support in the above photos.

Re: link to mustang gas tank install
 

It does weaken the support in that area. I would leave the cross member in and mount to the lower rail. The fill is a 2" at the tank, You would need a tight 90 bend and a fill neck. You may be able to fab the old fill neck to work. As for the tank support 1" square tube 0.90 (3/32) wall would be good, make a box and sandwich the tank between the box and lower frame rail.

Re: link to mustang gas tank install
 

What if I got rid of the leafs?
I have a rear axle under the truck from a '77 Malibu wagon.
Would I improve the ride by going with a coilover setup, & thus not need to worry about the lack of support from relocating the crossmember?

Re: link to mustang gas tank install
 

You only need the member in that position for the spring shackles. Using coils or coil overs you would move that member to the back because you do need something to stabilize the rear frame section and offer some protection for the tank.

Re: link to mustang gas tank install
 

It doesn't seem like moving the crossmember would be THAT big an issue with a street truck like ours that is unlikely to carry much; if any significant load. I don't think I'd be too worried about that.

If the tank bolted to the upper flange without additional support, it'll bolt to the bottom flange with no structural concern. So you're suggesting surround the tank just for collision protection?

I'm thinking Rudy bolted it as he did - on top of a square tube spacer - to increase the ground clearance. Plus, MAYBE(?) that spacer serves to allow the tank to be removed from below if you can take that spacer out?

What I like about his installation is you can buy. New mustang tank for less than $100 brand new. That makes welding it doable. I'd never try welding on a used tank, full of water or otherwise.

Re: link to mustang gas tank install
 

Ok, so I just checked eBay and there are lots of new Mustang tanks in the $100+ range all the way up to $700! Why the hell would you buy something for $700 that you could get for $100+?

What irritates me is that the otherwise-identical one listed there that is already configured to fit a '55-'59 Chevy truck is $218. Doesn't cost an additional cent to make the sending unit hole a different shape but they're sticking us for an extra $100 because they can. Damn.

Re: link to mustang gas tank install
 

The original tank is a bottom sender/pickup tube with no fuel tray for EFI. You then have to modify it for the correct sender or make some kind of adapter for it to work with a early GM gauge, You then need a pump that has a fuel tray adapt that to the tank. If your not doing efi then a $80 tank would work but may fail inspection because you can't use a bottom pickup tank in anything that it did not originally come in. Bottom pickup or a sump pickup are not legal any longer.

We did this whole discussion 2 weeks ago about $80 tanks.

Re: link to mustang gas tank install
 

The $218 one is for EFI and it does have internal modifications and external changes. Its nothing like the $80 tank and it won't work for a stock mustang car. Its coated steel and has the proper holes for EFI pump and sender. The $80 stock tank has one hole near the bottom of the tank for a pickup and sender. It won't work for EFI at all without a lot of modifications.

Re: link to mustang gas tank install
 

Ok thanks.

Well, I'm not doing EFI and there are no inspections on cars in California but still I'd definitely not want a bottom sender so back to the drawing board I suppose. It didn't look like Rudy's ("Rude Dude" above) was a bottom anything.

Re: link to mustang gas tank install
 

The tank at the top of this page is a bottom pickup/sender that he modified to use a top pickup on. Its in the from bottom of the tank. The picture is a stock tank.

Re: link to mustang gas tank install
 

Does the $200+ tank work with a carbureted engine without modification?

With the stock Mustang tank (lower priced) I'd have to not only weld shut the bottom sender hole but also cut a hole for a sender on top, AND figure out a way for the filler spout to come up perfectly vertical instead of canted to the rear as it appears to be in the pic's.

Re: link to mustang gas tank install
 

The $218 tank has a place for the sender and another for a pump or regular pickup tube. The pickup tube is about $30 and the sender is about $30 so for $260 shipped you just mount it and plumb it. No welding or making ford senders work with gm gauges.

Re: link to mustang gas tank install
 

Wheres the link for the $218 tank?

Re: link to mustang gas tank install
 

Its actually $210

http://www.hollisterroad.com/proddetail.asp?prod=MU-HT

It doesn't come with the cap shown. It comes with a bolt-on neck. a rubber gas hose and the gaskets for pump/pickup and sender.

Re: link to mustang gas tank install
 

This is the tank I'll be using for my 70 C10 from Tanks Inc. # MU-H it comes with with the location for the sender at the top and a 3/8 pick up tube at the front of the tank or the back, depending on how you look at. My only concern is how to vent the tank with out adding or drilling any additional hole in the tank I called Tank Inc, and they just said to use a vented cap, but there has to be another way to vent it properly. I got this tank on ebay for $204.00. I was looking for something I didn't have to modify too much, and since My truck is bagged, the tank sits up in the frame. I had a LMC tank in there before. It just looked to ugly, and sat too low.. If anyone has any suggestions I sure would appreciate it...

I hope this link works...

Re: link to mustang gas tank install
 

You don't have many options with that tank other than drilling and welding in a bung or drilling a hole in the sender and tapping a 1/8 pipe for a fitting or using a vented cap.

Had you gotten the MU-T you would have the pickup and sender in the top and the pickup for an MU-T has a vent pipe port.

Re: link to mustang gas tank install
 

I did think about the MU-T, but its a efi tank. Would it have made a difference? But drilling and tapping a hole in the sending unit might do the trick, sound easy enough....

Thanks Dave.....

Re: link to mustang gas tank install
 

The EFI tank has a fuel tray and a standard pickup can be used instead of a pump. Major difference is that it has the pickup and the sender on top.

Re: link to mustang gas tank install
 

Here's another way to do it with external electric pump. This is the tank I am putting in my 46. My plan is to start off using the sump hooked to the engines fuel pump. Then, if I ever want to switch to EFI, I already have the scavenge sump built into the tank.

Here's a bad pic but you can just barely see the supply nipple coming out of the sump.

Re: link to mustang gas tank install
 

You still have to find a way to convert the Mustang sender to a GM Gage unless your going after market. With the MU-T or MU-HT you can get the EFI tank, sender and carb pickup for under $290 shipped and its EFI ready and no sump. Sump connections have been banned in most states for anything but racing. If NJ DMV sees it they may fail your inspection.

Gas Tank Install Help
 

Ok,I am stuck on my tank install and I really could use some help, as I may have made the wrong choice in choosing this tank. Please bear with me as I explain my problem.After doing the research and taking all the measurements I thought I needed to take, I opted for this tank, a mustang tank ( 65 to 68 ) from tanks inc. This tank has been installed in other chevy frames with some modifications.
http://www.tanksinc.com/cartimages/prod_zm_311.jpg The measurements for this tank are 32-3/4''x24-1/2''x7-1/2'' deep..

This is what was in there before, the blazer tank.. pic#1

As I position the tank to try to fit between the frame rails, I see that it won't squeeze in at all. the measurements for the in side of the frame is 33-1/2'', the bottom side of the mustang tank is 29'' even from end to end.Pic#2 new tank up against the frame

In pic # 3, this is where I got stuck..The bottom part of the frame that you see is 3'' wide. In order for me to slide the tank between the frame I would have to cut approx. 1-1/2'' from each side. That seems to be a bit too much I think with out loosing any strength integrity of the frame. Correct?

In pic #4 The top part of the frame towards the front is 3'' wide and tappers down to 2-1/2'' towards the rear, but the bottom portion of the frame is 3'' even front to rear.

I don't know if its safe to cut off from the bottom portion-of the frame as I mentioned before with out making it weak..

I don't know what exactly I need to do here and could use some help or advice. I was told from the guy's at Tanks that people use this tank for a lot of under bed conversions with minimal issues. Is there something I can do to get this tank to work here? I'm not even sure if I can return it. This is a real headache right now.

Thanks everyone for any help you can offer. Sorry for the lengthy post, but thought it was necessary.......

Re: link to mustang gas tank install
 

old thread resurrection...

legotech7 did you figure it out?

I'm getting ready to order a Mustang tank and want it to go smoothly...

Interested to see how this went as well??....if do a image search....there's guy who put one in a 66(think??)...over jalopy journal years ago.....be good tank for doing rear mount if fits for sure!

Re: link to mustang gas tank install
 

Well found you have to cut 1.5" off each side rail to fit it in.....went way back in search function land...might just get a boyd's alloy tank..

Re: link to mustang gas tank install
 

Anyone running an Aeromotive tank with built in fuel pump and sending unit? I was looking at their unit for my 1956.

https://www.summitracing.com/parts/a.../model/mustang

Re: link to mustang gas tank install
 

that's not at all true. I have been using a stock 65 Mustang tank without any fuel tray for EFI at all for over two years and that's with a 5.3 fuel injected motor. Unless you are slomning or quarter mileing on a near empty tank, you will not go side to side enough for the fuel to go away from the pickup

If you want to see how it's done check out my 49 build in my signature.

Re: link to mustang gas tank install
 

"The $218 one is for EFI and it does have internal modifications and external changes. this is definitely true


Its nothing like the $80 tank and it won't work for a stock mustang car. This is also trueif your attempting to use a stock sender pickup on the EFI tank .

it Its coated steel and has the proper holes for EFI pump and sender. Again also true.

The $80 stock tank has one hole near the bottom of the tank for a pickup and sender. also true.

It won't work for EFI at all without a lot of modifications"
It would work with a stock sender to plug the hole in the bottom and using an pump like a PA series. or an external pump with the stock sender and pickup so its half true

I can agree with you here somewhat, You may or may not have a starvation issue without the tray but for the price of it I prefer to have a tray in it or a pump that has a cup.

Re: link to mustang gas tank install
 

Okay, for the price it is good to have a tray. What I run is $70 mustang tank. I'm using the stock fuel pickup, an external pump, and a corvette style fuel filter with a return. On top of the tank I just drilled with a hole–saw for the stock brand-new sender. And I put a brass 90° elbow for the return into the tank. I was just saying that it wasn't necessary to have a tray.

Re: link to mustang gas tank install
 

I saw your page on the setup. Most likely with that short of a return it may not starve. I would expect it to blow any air back into the tank rather quickly.

Re: link to mustang gas tank install
 

two years now, and no problems yet.

Re: link to mustang gas tank install
 

Regular cheap tank. Sweat out the stock fill pipe and added the tanks inc filler myself, then put the vent/ roll over valve in the cap. I've got some 3/8" weld in bungs to add in the bottom corner of the tank. Probably won't bother with a sump. Mechanical pump on the motor, and possibly an external fuel pump on the frame rail of we need it. It'll be a turbo & efi motor. Had to trim the insides of the frame rail 3/4" on each side for it to slide in, and then I nutserted the tank and bolted it under the top framerail so it looks like it's supposed to be there. Still need to add a rear cross member back in. Probably just 2x3 angle so it captures the tank, but it can be dropped and slide back out if needed.

Re: link to mustang gas tank install
 

i used the 65 mustang tank from tanks, inc. very happy with it!

Re: link to mustang gas tank install
 

Is your truck a '57 stepside?
You using a stock rear bumper, or roll pan?
Did you end up using a flexible hose from the fuel neck, & a flip up or down license plate door.
I assume that bend for the fuel neck is a 70 degree from tanks inc.
I paid a fab guy to 4 link my rear, & install the mustang tank, but he shimmed the tank down below the frame rails, then he installed a 90 degree rubber fuel neck.
Looks like crap, & can't put a fuel nozzel in it.
I'm thinking i need remove the 2" sq tubing shims, install the same fuel neck as you.
Please advise

Re: link to mustang gas tank install
 

He mounted above the lower rail and had to trim the frame to accommodate the tank. I remember selling him a 70 degree neck and it should drop just under the rear cross sill. Use a 2" ID short rubber hose to connect to a fill neck and you should be good to go. You can get a flip down plate hanger to hide it and you will have to fab a little hanger for the fill neck.

Re: link to mustang gas tank install
 

My brother came over today, pulled the bed off.
So from what I've read here, & what your saying, is in order to slide it in between the frame rails, the rear cross member needs to be relocated further back, & 1 &1/2" inches has to be trimmed from the frame rails.
Another option I'm considering is the 59-60 car gas tank, & cut down the fuel neck.
Would either install result in about the same ground clearance?
