This past Saturday I finally got around to starting the install of a Fitech EFI system on my Roadrunner. Drained the fuel from my tank and removed associated fuel pump, filter and lines. Installed to supplied filter and EFI pump along the frame rail, ran the EFI hose to the inline filter and carb with no issues. Previous owner had installed a Moroso fuel pump, regulator and 1/4” (?) return line using metal lines with a shirt piece of 3/8” fuel hose to one of the vent tubes at the tank.
The original vent line to the tank is a tiny 1/8” (?) barbed stem, doesn’t seem adequate for the return line, not to mention the hose size diameter difference. I don’t think this is a secure transition from the return line, at 50 + psi?
Any suggestions for the return at the tank, do I need to add a larger port for the return? Shouldn’t it extend into th tank a ways to prevent aeration close to the pick up?
I am not opposed to upgrading the stock tank to a newer replacement if needed, mine has a few dings and dents as well as being old. All the stock replacements I find offer the same vent configurations. Curious as to how others have plumbed the return?
Another issue was The was the throttle cable attachment to the the throttle body, neither the stock hardware I have, nor the Edelbrock Mopar adapter seem to provide the correct attachment and travel. I don’t see any offerings on the Fitech site, what worked for your application?
Thanks in advance,
Mark
