    Default WTB: Citroen CX 2400 mechanical fuel pump

    Trying to get a 2400 Pallas ready for sale.
    Unfortunately there is no fuel being pulled up from the tank.
    Pretty sure its the fuel pump.
    Putting out feelers for anyone with a spare pump laying around.

    Hi Projet_L,

    Is it possible that the pump has just lost it's prime? try starting with fuel down the carby throat or ether and see if it comes good...

    Cheers,
    Andrew

    Also, check the pickup hose for cracks as even a small air leak will prevent fuel being drawn from the tank.

    Thanks for the tips
    Yeah did the fuel in the carb trick to begin with as it hadn't been run in quite awhile.
    Pump wouldnt prime. Filter was not filling. The line from the tank to the pump is dry.
    Put an extension onto this line so I could suck the fuel up. No luck and a head ache.
    Could be blocked down the tank end?

    Forgot to mention the pump is delivering a pulse to the carby side line. Not sure how strong this should be though.
    Also the intake side hose seems to be cracked a little on the end, could it be sucking air. hmmmm.

    If it is an intermittent use car, apart from all the fuel line/cracking/blockage issues, I'd go for a standard electric fuel pump and put a plate over the standard fuel pump mounting place. Best modification I've made to my CX 2400.

    Something like this: https://www.ebay.com.au/itm/401445346752 FuelFlow # 015 Electric Fuel Pump 12 volt 1-4psi Universal High Quality NZ Made Also, don't use ethanol fuel in a car not used regularly unless you want corrosion of the tank and tank unit.

    That's very polite David. I'm very reluctant to let ethanol in contact with my car for any time at all.....

    But the electric pump just transforms a car in intermittent use.
