Fuel pump options for a 2.4 Bridgeport EFI

[pyro]

I took a nut-backed tire valve stem, removed the valve part, drilled out the ID a bit bigger, and ground off the threads on the last inch of the tip. I installed it into the side of the fuel filler neck for my return line. Works great.

I'm NOT a big fan of the idea of using the spare IN port, as it closes the fuel loop and will re-circulate air bubbles if your fuel runs low and sucks up any air... This can cause a dangerous lean condition. The Vegas tank is wide, so it's possible to draw air occasionally in a turn.

My setup has been the same way since 2006.

Also, make sure your vent line makes a tall roller-coaster loop between tank and fitting to keep water from getting in.

Just doing a little research and came across this old thread via a google search. Moeller now makes a fuel level sender with a return fuel fitting in it.

Just an idea. Could it be because you are returning to the extra "in" port instead of the fuel tank that your fuel is hotter & causing premature failure. I've heard that people that constantly run their cars low on fuel have more than average pump failures as they run hotter. I run a separator before the pump, then an inline after, but I return to the tank. My Viper fuel tank does not have an extra fitting so I installed a tee in the vent & return down through it.
