    Awesome helpful post thanks Clive!...much appreciated.
    Will get onto it today....
    The mechanic replaced both fuel filters, so at least i think they are okay!
    My money is on the fuel pump...either it is failing or the wiring is shot.
    The way it looses power going up hills could be explained by a weak pump....

    Yes attached to an outrigger with rubber insulators. There should also be an earth braid between the pump and chassis.

    Found it....first thing is i have a black earth, but the braid earth, while there, is broken!....Does the pump have 2 earths, the black wire and the braid??
    If so, where exactly on the pump does the braid go to?? The Black earth wire is intact and connected to the fuel pump, and I cleaned up the earth screw to the chassis....

    The black earth wire should be enough. Someone has bypassed the original broken earth braid.

    Thanks mate. that is what I figured
    Looking at the pump, I think its not the original....Googled what the original one looks like and this one is likely aftermarket....Looks super old!
    The good news is that it is all working at the moment, so I will take the wait and see what happens approach...will buy a replacement pump any way, just in case
    4-6 psi is correct from my google effort!

    Hi

    My 85 County pump has two earths as well.


    I'd still be isolating whether its a blockage or the fuel pump before spending too much time or money.

    In my experience losing power going up hills whilst OK on the flat is signs of a blockage. Unless it intermittent electric supply from the wiring fuel pumps tend to work or not.

    The needle and seats are easily the narrowest part of the fuel supply system and need to be checked.

    Good point!....She is booked into the mechanic again next week to adjust the timing after the new muffler went on, so i will get him to have a quick look at the carbys.
    Any point running thru a carb cleaner?? used to work on the Lada Niva's
