    The potting does not seal fuel. The brass cores in the plastic have O-rings on them which seal the fuel. The connections are soldered to each end of the brass core.

    Ok. Does fuel attack solder ? Or did Aprilia just do a poor solder job ?

    No, I don't think fuel attacks solder. I think there were just a lot of poor or cold soldered connections.

    Our ethanol laden fuel does attack the OE potting however.

    Hi
    Thanks for the info. I checked the fuel pump connector located next to the battery and there was power coming to it, but I haven't checked from connector to and around baseplate, but will do now, thanks. If that seems fine is it worth removing the pump and checking that

    You can check resistance across the fuel pump from the harness. If it's infinite, you'll likely need to dig the potting out from both sides to get at those connections. If my experience is repeated, the inside potting will dig out easily with a small, sharp screw driver. i had to carefully drill and dremel most of the potting on the outside.

    After it was al soldered up, I used the Caswell stuff, but JB Weld will likely hold up well.

    Update, the problem was a loose wire going into the pump. A bit tricky to fix but it's now done. Thanks for your help.
