    Help! Petrol tap (gas cock) weirdness

    So, I finally forked out nearly £100 for a new, genuine, complete petrol tap for my GS1000G, as nothing seemed to make the old one stop letting petrol through. I've just taken the old one out of the tank and I found, to my astonishment, that the two mounting screw holes go right through into the void. I had expected them to be blind holes, but no.

    So, my question is, how shall I make sure there's no leakage when I re-fit the new tap? The old one had some sort of blue goo all over the 'O' ring and the screw threads (looks like Hylomar but I didn't think that was petrol-proof, so i guess its something else).

    My manual tells me there's no need for any gasket sealant. I don;t believe it. Can anyone with experience of changing taps please tell me what brand of stuff to use (and preferably where I can get it)? I don;t know of anything petrol-proof.

    There are two special washers under the bolt heads that have rubber surfaces to seal them.

    There is a name for that thpe of washer but I don't remember what it is.
    If you're not living on the edge, you're taking up too much space.

      The correct washers have little rubber O rings built in. Suzuki still sells them, as do fastener supply places.

      Suzuki part no:

        dowty seals, or dowty washers.

        1978 GS1085.

        Just remember, an opinion without 3.14 is just an onion!

          Thanks to all three of you who've replied, this is exactly the info I needed. The washers that were fitted were just plain steel washers, hence the liberal use of gasket goo I reckon.

          I'll phone Robinsons Foundry in the morning and get the proper items.

          Thanks again all, this is the kind of thing that makes this forum good!
