I put a '97/'98 LS1 into my 85 C10. I plan on running a 91 suburban tank under the bed or a cell, but I'm not sure how to plumb the fuel lines in. I believe I have returnless style fuel rails, and I'm not sure what to do with the return line off of the sending unit.
The return line needs to come off the rail back to the tank.
You can use the return line on top of the fuel bucket if that's what you're asking.

Failing that, like if you wanted to run boost you could run an external reg but you would have to run 2 lines the lenght of the vehicle. I've never done it but that's my understanding.
