Hey Folks,
I want to go with an electric fuel pump in my gas tank (Walbro TBI pump with reservoir tray that puts out 12 psi) and while I was thinking about how to install a return line from the regulator back to the tank, it occurred to me that there's already one there from the factory. The stock fuel filter ties into it, up front by the mechanical fuel pump. The return line looks like it's 5/16-inch, like the fuel line, so I'd like to use the return line for my new setup.
Have any of you done this? Or do you know any reasons it won't work? I want to use the stock fuel line from the tank forward, with a Quick Fuel Technology 30-9000QFT return regulator to get me down to 5 psi for a happy carb. Otherwise the car's a bone stock '86 Fifth Avenue and it runs pretty well. To delete the LeanBurn I rebuilt a Holley 2280 carb in place of the 6280 feedback carb and installed a plain old Mopar vacuum-advance distributor with lighter springs on the weights and an advance-limiter plate in it.
But I just put a new mechanical fuel pump & filter on it in February and the pressure is anywhere from 2 psi to 6 psi depending on the outside temperature and engine temp. I'm tired of fighting with mechanical fuel pumps. I just want a reliable, quiet, consistent fuel-delivery system for my 318 daily driver.
As always, I look forward to your good advice.
Thanks.
