I mocked up my filter/regulator in several positions but I wanted to have it in the most accessible location for future maintenance. By mounting here I will be able to change it out fairly easy and it will keep my feed and return lines short. My stainless line clamps didn't show up today so unfortunately this is as far as I got and I wasn't able to run the main line from the filter to the fuel rail.

I'm curious so I'll ask.... Is there a reason why you didn't run hard line for the bulk of the line & just the braided for the flex needed @ the ends?

What's the service life expectancy?
Would you share the costs?

I ask because I sure want to do my 64 w/all flex line but many discouraged it. I felt if I set it up right, I could simply add it to a maintenance schedule for replacement @ certain intervals. Routing the hard line through all the boxing/bracing w/the PB components up front is a PITA (I did plumb it with 3/8" hard line already but I guess I should have put it in place before bolting all the front suspension pieces & brake lines into place). Really, really, would prefer to not have to disassemble all that & I might want to upgrade line size @ some point when the truck gets a new heartbeat.

Re: 1970 Med Olive Project

Scoti,

If we were talking about standard braided line, I would agree that you would need to service (replace) the line every few years because they will not hold up to pump gas and all of it's additives, especially in areas that use ethynol. I have always ran Pro-Lite 350 on all of my race cars and have gotten years of trouble free service running race gas. The cars we ran methanol in though, we would start seeing the lines start to soften after a couple of seasons. I will never run the pro-lite on anything that will see today's pump gas though.

The BMRS lines use a PTFE liner that is impervious to all fuels and additives and will most likely outlast the car that your are puting them on as long as you keep them away from heat and keep any moving parts from rubbing. They are lighter and more flexible then the Pro-Lite 350 as well.

Here is a link to what I am using. High Temp Polymer Braid. They have crimped fittings and BMRS pressure tests them to 250PSI. http://www.bmrs.net/PTFE_hose_01.html

I will confirm when I get home but I'm pretty sure I have right at $275-$300 in all three lines and fittings for the cell. Yes it's a little pricey but like I said, they should outlast my truck. Anything I can use that gives me piece of mind and has little to no chance of failure, I will willingly spend a little extra $$ on. I will add that if you order these, ask for the swivel fittings so it's easier to clock your fittings at the pump, fuel rail etc..

That's not bad @ all for all 3 lines w/the appropriate fittings. And snaking a flexible line through the DM frame rail gussets would be far easier vs trying to get the 3/8" hardline in place (& def easier if I bumped up to 1/2").

I shall check into this. Thanks for the info & the link!

(I only hope they have black anodized fittings)
