    my mechanical fuel on my 2 litre 77 kombi
    was not functioning properly
    so the mechanic put in a electric fuel pump...said it would be much better...

    am now on my 3rd electric fuel pump.
    would like to go back to the original mechanical fuel pump.
    been told you can't get them .
    is this true ...have others got a better solution?

    Hi Jerome,
    Wow...still got my original:cool:. Must be a 'why' they're being 'chewed up'. My guess is voltage;). Got the right relays? Bit important:rolleyes:. LHS of engine bulkhead has relays for your fuel stuff. May be some difference? for mech over electric?
    @rstucke or @1500king for further questions. Cos I'm no good at this:D.
    Cheers

    must be something like that.
    i guess its easier to swap out the fuel pump then figure out what the real problem is.

    Mech fuel pump not so easy to deal with. That's why you swapped it in the first placeo_O.
    Chase the voltage:D.

    I fitted an ebay cheapy about 7 years ago $16, 4 to 6 psi, there still on there and it hasn't missed a beat, so cheap I bought 2 and am still carrying around that spare unit .

    The cheap ones can be hit and miss for pressures.
    A good mate who owned a spare parts business supplying most of local garages tested a box of them after issues were raised and found considerable number had pressures all over the place.
    Stopped stocking them based in results.
    Best to check each unit if fitting or fit a reliable pressure regulator.
    The chrome empi don't seem to be a good choice in that regard either.

    i find the genuine Facet lift pumps to be good quality, they are however a little loud but you dont notice it once the engine is on.

    Thanks for that link MY74. Had to chuckle a bit at some of the Dutch words for things eg. now I know what a Krukas & nokkenas are. Crankshaft and camshaft. I always thought I might have had a bit of a problem with my nokkenas !

    Rebuild kits are no longer available for the mechsnical ones.
    Replace with a pierburg lift pump rated at 3-5 psi. Any more and you risk damage to the needle valve in the carb.
    Also make sure you have a relay (tachometric) to switch it off if the engine stops. They are available from JK. Peel CP30 I think the number is.

    Adrian, dumb question but what was in a rebuild kit?
    I'm struggling to work out what can't be replaced in some way?
    The diaphragm itself would have to be the main thing. Is it metal or a synthetic?
    How can you test the condition of a mechanical pump to assess it's health?
