I am swapping in GM TBI and I am wondering what you guys do about plumming in the fuel lines into the gas tank. Also what fuel pump are you using?:roxy:

I have a 1969 and found it easiest to leave the tank alone, remove the fill neck from side of cruiser and tig weld a a steel return line into the bottom side pointed into the tank so the gas station fill spout won't interfere with it I think it is was tubing I had from my old fuel pump, but dont quote me.
If you look at the fill tube you can figure out what will fit and where it will work for your application.
Good luck

I use low pressure rubber lines from the tank to frame and an MSD inline fuel pump (http://darkwing.uoregon.edu/~jrice/cruiser/MSD-2225.jpg) mounted on the inside of the frame. The image below shows the steel lines (painted red) mounted on the inside of the frame.

I also use a high-pressure rubber line from the frame up to the engine. This section of the plumbing also includes a hi-P fuel filter.
HTH :)

Ford pickup trucks (mid 90's I think) had surge tanks that can be used for a reservoir. Also there is a fuel pump, Master PN E2182 that works for TBI applications.

For the funky fuel line fittings on the engine hoses these P/Ns have the 3/8" and 5/16" Saginaw fittings on about 18" of hard line to make plumbing the system easier...

I used a reservior in my system to account for an unbaffled tank. EFI does not like interuptions in fuel delivery... I used a cheap carburated style electric pump to pull from the tank and send it to the reservoir. Then a higher pressure pump(E2182) draws from the reservoir to the fuel lines on the engine. Ensure you plumb a return to the reservoir from the engine and a return from the reservoir to the tank. Post '72(I think)tanks have return lines already so EFI conversion on them is easier. It is the line that runs to the tank and enters the tank on the side, not underneath. You'll see what I mean with the seat and tank cover off.

For a reservoir I converted an old '78 FJ40 charcoal canister into a reservoir by brazing in steel lines and brazing a lid ontop, but you can use the ones from ford trucks, there are some actually designed for dual tanks...So you could use a stock tank and Aux tanks with one more fuel pump... The same ford trucks use a switching valve too that route both supply and return to the selected tank...

Hope that helps....

Do you know what working PSI that works at?
Thanks:roxy:
