Gas tank return line?
I'm considering using a fuel injection system on a new SPF cobra (I'm planning to buy) which requires a fuel return line to the gas tank. Does anyone know if the car comes with a return line or at least a port to install one? If not has anyone done this? I'd appreciate any info I can get.

Easy enough to weld one in with the appropriate safety precautions.

What fuel pump are you planning on using?
The reason I ask is you might want to look into a different tank, or create a seperate surge area. This has come up before: http://www.clubcobra.com/forums/superformance/90431-great-asps-superformance-fe-build.html Page 16 starts my tank build. You can email me directly for details. E |
Run the return line back to the overflow line at the fuel filler. Cut a tee into the line and it's done. Or....weld a permanent solution by welding a return directly to the gas tank as suggested.

I am running EFI in my SPF, (2734) , you will need to add a return line, it can go into the filler neck vent just fine. --
I added a fule accumulator ( of sorts, ) but I think I will have to go back in and baffle the tank, or add a fuel tray. Driving issues, under 1/2 a tank of fuel , and if you slalom a bit, == you can have air cavitation in your fuel pump/feed. Steve |
There is a baffle in the tank, it runs longitudinally in the tank, about 1/3 over from the drivers side. I has two holes in it, one bigger than the other.
Your statement on 1/2 full is correct, but also in acceleration there is no feed to a high pressure pump using the stock bung. E |
