Re: 77 c10 5.3ls turbo

Truck is looking great. I have that TA girdle as well. Looks great until it oxidizes...

Did you use the 87 sender in your original fuel tank? Im considering dumping my fitech fuel sump and wire/plumb and electric pump in the tank. And those Russell fittings fit right on that sender?

Re: 77 c10 5.3ls turbo

I did use the 87 sending unit. I had an AcDelco Ep381 pump that mounted right up, wont support what im doing now so I switched it for a Walbro 450. That mounted right up as well. Yes fittings mount right up. I went with the in tank pump because it is quieter.

Thank you.

Have you looked into needing a sump to keep the pump from starving? I found a guy on YT that built around the stock setup using a suction jet pump. Im curious if that would be worth doing on a non-efi tank.

I have not. Hope my setup will be good as is.

Re: 77 c10 5.3ls turbo

Nice build! One critique, I only saw one picture of the turbo oil drain going into the timing cover so it may not be an issue. But in that pic the fitting on the timing cover is pointing down (I think) and not optimal. Turbos can be sensitive with the drain and it should be as direct as possible for the best flow. Otherwise oil can backup in the line and go past the seals.

Re: 77 c10 5.3ls turbo

When installed fitting is pointed up. Keep the critques coming, this is the first time i've done this and relying on the internet.

Re: 77 c10 5.3ls turbo

He's right the oil drain is a very important part of the turbo but I have a friend who put his in the timing cover like that and has logged 16000 miles without a problem. Mine is in that spot as well, I wouldn't worry about it.

I wasnít concerned about it being in the timing cover. He posted a pic with the fitting pointed down, no hose attached yet, so I wanted to verify the drain hose routing. Thanks for chiming in about the timing cover drain though, always nice to have more input.

I had no trouble telling which end of the timing cover was up and the hose can only go down from the turbo so I'm not sure what you were looking at there, so i didn't want any misinterpreting of your comment. He's doing a great job on this truck from my perspective.

Re: 77 c10 5.3ls turbo

That is the crossmember below the crank pulley so the 90 degree fitting is pointed down. It may be obvious to most to point it up towards the turbo but for someone new they may have a less direct path in mind for whatever reason. Maybe I missed it but I didn’t see the drain in other pics so I posted to be sure. I think we both may have misinterpreted each other a bit on this one, it happens, time to move on, but again thanks for chiming in and I agree he’s doing a great job.

Re: 77 c10 5.3ls turbo

Got the axle installed and drag radials on. Still need to finalize rear diff cover install and brake lines. Should finish that tonight. High 20's here so I have to work an hour or two at a time. Driveshaft and shocks are all that is left, besides final tuning and whatever problems come up. Plan on painting white walls on the rear tires to match the front, but that will have to wait until it warms up. Innovate AFR/boost appears to be working but I still need to read the manual to see if I have to calibrate it.
