    Fuel pump advise please

    i am experiencing problems with the running of the car. in have a blue facet pump fitted the the top of the inner flitch panel, the darn thing constantly sounds like a traction engine, i have sucked the fuel up to the carb and refitted the pipe, for a while the pump then runs quiet, then it starts to get noisy again, when this happens the engine suddenly doesnt rev, i have then checked to see if there is fuel in the filter but its empty, i again pulled the pipe off the carb and can still suck the fuel up, my qustion is , is the pump nackered or is it that its fitted to far away from the tank or is it fitted to high from the fuel outlet pipe , any help or advise on this will be very much appreciated.....steve

    Well first thing is the pump should be mounted at the rear as they are fuel pushers not pullers.

    i have my fuel pump close to the tank, and fitted low down on the chassis rail so fuel will run from the tank to the pump quite easily.
    If you have a plastic in-line filter they dont always 'fill up' with fuel, the fuel tends to trickle through them. i used to worry over this as I expected them to be full to the max, but they dont seem to do this, well mine doesn't anyway.
    i also have a non return valve fitted between the tank and pump so any fuel further up the line doesnt run back when the car has been left idle for a few days. The electric fuel pump has made a huge difference to the running of the car. One of the better mods I have carried out.

    Another point is that I run my filter after the pump to prevent the problem Dan has mentioned, A lot of people say that the filter should be before the pump but i was told by Facet that the pumps can handle small solids without any problems, Run Facets & Holleys like this for the last 30 years and i've not had any problems.

    Steve, I guess your pumps are putting out a high pressure.
    Mine runs 6 to 8 psi (and on 6volts!) and the supplier suggested filter before pump. i also have another filter in front of the carb too for good measure.

    You need to prefilter on rotary high pressure vane pumps even though OEM don't do it that way. Slightest piece of crap will lock them solid so although fine with a new tank sticking them on an older car may see problems.
