    Fuel pump stopped working

    I have the fuel pump you can see on the link below:

    https://roadcraftuk.co.uk/index.php?...product_id=347

    It is going to a Edelbrock carb then into a SBC 350, all installed in Gen II AK.

    When running the car today it suddenly stopped working. Car had been running for about 20 minutes absolutely fine, then switched off and then ignition on....fuel pump whirred as normal then suddenly stopped before I started the engine.

    So two questions really:

    1: does anyone with experience of this type of pump know if it should just be pumping continuously with just the ignition on?

    2: any ideas what could've gone wrong?

    We didn't have time to check it out tonight, but will double check the pump is still good tomorrow. Checked the fuses under the dash and they are ok.

    Just seeing if anyone has any advice to assist in the problem solving when we get back to it tomorrow.

    Kit has arrived.....follow my progress here at my blog:

    Unsure why it’s stopped working but, just to confirm my similar unit runs constantly.

    I have the same pump. The push on connections on mine weren’t great and could work loose. Make sure they’re pushed on. I made a L shaped bracket to keep them pushed on

    Cheers Peter....one of the first things to check I think!

    as Peter says - check connections. I had my pump cut out whilst driving not long after it was fitted. Looked to be still connected, but wasn't pushed on far enough (probably never was). Been fine ever since.

    Cheers All - glad to say it was indeed the connectors, so easy fix.

    It seems the metal clips inside the push on connector had spread a bit wide (I guess maybe pushed on too firmly in the past and it was squashed slightly?) so the connection wasn't being made properly.

    Will look at it in a bit more detail to see if there is a better fix than just crimping the metal clip back together.

    No to try and trouble shoot some other gremlins like headlights (except main beam) not working and water temp gauge not working.

    'water temp gauge not working.'

    - have you fitted a voltage regulator to the gauge, and are the connection to it wired correctly?- that last one caught me out last year on a similar gauge.

    Cheers Kev,

    Will need to get the dashboard out to take a look, but good tip.

    Thanks

    Good news....fuel pump was indeed the connectors on the bottom of the pump, so that's working again.

    Water temp gauge was fairly simple but needed the dash out...temp and Speedo gauge plugs just needed swapping!

    All in all fairly simple fixes.
