2.4L Bridgeport w/electric fuel pump

**Chillaxed** · 03-27-2017, 08:14 AM

Question regarding electric fuel pump on carb'd 2.4l Bridgeport: should the electric fuel pump constantly run or should it cut off once a certain pressure is built up?

To me, I would think that it would shut down but this is motor and "previous owner set-up" is new to me. If I switch the fuel pump on without turning the motor over, the jets will begin to spill fuel into the bowls and continue to do so until I flip the pump off.....doesn't seem right or safe.

Any advice or suggestions on setting up the fuel system properly would be much appreciated.

Yes it should run all the time.If this is a carbed BP then you need a low pressure pump,regulated to maintain 4-5 PSI @ the carbs.Sounds like you ether have a non regulated low PSI pump, or possibly even a EFI pump witch will not work.

Ok i appreciate the response...motor ran great on saturday...running low 70s on gps but still learning how to drive her. She didnt like to idle too much when in gear, but believe that is due to fuel overload. Im gonna pull the pump this week and do some further research on it and see what i find out about it and whether it needs replaced. Thank you again

Carter makes a low-pressure pump that we have used carb applications. It runs while the key is on with no probs. Some guys are using a red Holley pump with a regulator tee'd into the pressure side to dump back into the fuel tank or supply hose. You need a pressure gauge to properly set the regulator. I think someone posted a diagram on here a while back on how to set it up.

Put a Holley regulator on it , oriellies normally Carries them

I have mine dead headed into the reg and from the reg to the carbs. Thinking about running a return style at some point.

Also if the problem comes and goes it might been a worn out needle and seat or trash in it. I just had to replace a couple that was doing that.

With a regulator you can run the efi pump. One less step when switching motors. +1 on the carter pump. No regulator needed and I have used them on stock 150's to 245's with zero issues.

You also could have trash in between the needles and seats. My wh 22's would not leak with a blue holly dead head set up. Mike

You need a special regulator to bring an efi pump down enough a carb reg can't to it and neither can an efi reg, you need a efi to carb reg.

and a good blue blew the needles straight of the seats on a blue with a fugged up reg that would only get it down to about 15 psi.
