The Stovebolt Site Forums The Shop Area Engine Shop Fuel Pump??

When I bought my 54 pickup with stock 235 the PO had added an electric fuel pump and bipassed the original pump, he left it in the motor but is not plugged on either side of the pump. Does that matter in the way the truck would run? I want to go back with the old fuel pump should I just order a kit and rebuild that one? Is there any advantage or disadvantage to the electric pump or mechanical pump? I just don't like the way the electric pump has that added on look with rubber hoses and clamps?
Thanks

Some electric pumps have a habit of causing flooding problems, due to high fuel pressure. If you choose to leave it in place, hide it back near the tank outlet out of sight. I've seen people gut out the original engine-mounted pump and run a straight-through pipe to cary the fuel, with the electric pump mounted near the tank outlet. It's a good idea to wire up a relay that triggers from engine oil pressure in series with the pump, so if the engine stalls the pump doesn't fill the crankcase with gasoline. I've seen several cars and trucks with gas dripping out of the tailpipe, or the crankcase vent from a runaway electric fuel pump.

Put a new mech. fuel pump on it & put a spring return switch to the electric pump. That way when it sets for a long period you can fill the carb with the electric pump. Mount it in the frame back by the tank like HRL say's & put a filter in front of it.

The two guys that posted first are very knowledgable, but if it were my truck I'd throw that electric fuel pump in the trash and put a new mechanical on it.

You could possibly rebuild the old one but for the money difference, I'd use new.

If I decide to go this route will the fuel run through the electric pump without it being on when it is not needed? So the object would be instead of having to pump the mechanical pump after sitting awhile I could just hit the switch and give the carb a jump start fromn the electric pump correct?

You will have to tell us what part number and brand the pump is.Not all electric pumps will allow fuel through them when off.It might just be easy to check it on the truck running with your new mechanical pump if you don't have that info ?

The fuel pump I am looking at is a Facet brand it looks like it is available in 3 different presure choices from 2.75 PSI to 8 PSI what is the ideal pressure I will need for a stock 235 motor?
