I've been looking for the 1/4 inch sealing washers recommended here with no success:(They're $1.20 in the US which means probably $3 or 4 in Canada:rolleyes:Shipping costs would eat up any savings ordering from the US.Any suggestions?PN is GASKET 09168-06023 FYI.
 
What bike??? Maybe you order and have them shipped to me and I mail them to you...cant see mail being more than a dollar or so.
 
I'd like to find something I could find here,those Dowty washers might be the ticket.Same seal for both the 750 and the 1000 as I'm using the good 83 750 petcock I have here as my 1000 tap has a busted diaphragm.No money in the PayPal to order anything right now:grumpy:

Found them at Ace Hardware here in the states. I ordered some from Suzuki to use when I get around to it. The sealing washers I am using temporarily have neoprene gaskets which are not supposed to be totally gasoline resistant.

OK that's good to know.Hmmm....what to do now?Tried a home brew of RTV silicone I let sit on a washer to harden,it just peeled off when tightened.

Now I found that a really good question.I was looking at the 82 GPz petcock thinking it was the 1000's:rolleyes:Something was wrong with that obviously as a eBay search was showing a top sealing O ring with bars across to seal off the bolts.Hmmmmmm......try a petcock rebuild kit for the 78 1000 tap or throw the 83 750 tap on it?Might do the later and order a kit for the 1000 tap and:pray:it works.Still need sealing washers,not having much luck:(

In a pinch I have used a standard crush washer & thread sealant. Just be careful not to push the sealant (or RTV) up into the tank. Worked fine :)
 
My GS850G's petcock has been wearing black nylon washers from the hardware store for over ten years.

Just plain ol' 1/4 inch ID nylon washers. White nylon would work the same as black, but they had both and I figured black would look a little better.

Nylon is not affected by gasoline:

I'll continue the search for Dowty washer if the trip to the local dealership turns out to be as expensive as I expect.I do like the nylon washer idea,it's not like there's a lot of gas it's got to stop.On a side note I took apart the 1000 tap and it wasn't nearly as bad as I thought!Really just needs a top "O" ring the reason for a dealership trip.Off eBay it's $16 with the shipping to Canada:eek:Figure even the rip off artists up here can beat that.
Edit:The more I think about it the better the nylon washer sound.Thanks Brian!

Those are not dowty washers. The nice thing about the OEM/dowty type washers is the outer washer is steel, and there is an inner rubber sealing edge. You clamp down the screw and it's a metal to metal interface so no worry about torque falloff. With a compressible washer such as those rubber pieces the clamp load will slowly release as the rubber compresses. Plastic washers such as Brian suggests do this much less, and slower. I'd use those if someone doesn't want to wait for the proper OEM washers. Kawasaki used similar plastic washers on at least some of their KZ family bikes (my KZ750E for example).

Never said they were dowty washers. Just an alternative that is much like the OEM washer.

Actually they're metal topped with a rubber sealing surface. They're also concave shaped like a spring washer so they don't release pressure as the rubber contracts. Have had them in my bikes for years. No deterioration over that time and no leaks. Mount them with the rubber surface facing the tank and the metal towards the bolt. 1/4 inch works great.
 
As far as I can tell the OEM washers look line the ones JTGS850G posted.At least the ones I've gotten off various bikes have been.I'm going with bwringer's nylon washer idea backed up by a bit of RTV on the bolt just to be sure.We did go to the dealer yesterday.I got a shock when the parts girl told me that it was $8 for the "O" ring.Could have dropped me with a feather,sure you can get them for $4.50 in the US but shipping and the weak CAD will make it mute.Note to self check the dealership here,it might not be as bad as I think!
 
When I can't get Dowty washers, I smear under the bolt head, both sides of a steel washer, and the mating surface of the petcock with Hylomar. Let it set for two minutes and assemble. They never leak.

That sounds like a plan,don't remember seeing it here but I'll be looking for it now.Did get the nylon washers but I like the idea of something more.
