Fuel joint

[robdangereux]

Hi all I have a gs750 1980 UK model with vm carbs I am leaking at the fuel joint where
the tee enters the carbs. There appears to be a kind of sleeve as opposed to o rings.
All lists point to o rings, but there are no grooves for the o rings to sit in? Can any one help?
Cheers Rob

Some of us have had some luck soaking the tee in petrol for a day or two, I tried it but then settled on the aluminium tee from Z1 (it has o-rings).

Recently had the chance to try out putting o-rings on mine and it works quite well. The ones for mine where size -011, they're a standardized 11mm ring and the local auto parts store had them in stock.

There are various aftermarket metal fuel Tee's on the market. Ebay should provide some enlightenment.

replace all of them with aluminum ones with orings. My opinion is these dipped up pieces of sciit suzuki came up with is possibly the worst fuel management idea ever

Made these just recently for some KZ VM26's...

Now I know the Z1 tees fit will grab some. Thanks again

I don't know about the Z1 Tee for the GS750 but their Tee for the KZ1000's have O-rings that are too fat. I had to swap them out for something thinner. That's one of the reasons I decided to make my own in subsequent builds (since I have a lathe.)

Yeah, they're too fat for the 750 too, The Robert Barr kit fixed that though.

I've had success in carrrrrrrrrrreeeeeffffuulllllyyyy cutting out the raised "o-ring-ish" bits of the crappy rubber coating with an X-Acto knife, then installing o-rings in the resulting grooves.

You might also be able to soak them in a mixture containing methyl salicylate (wintergreen oil) to swell and soften the rubber a bit. I've done this with other rubber parts and had some success.




But honestly, I'd just replace the damn things with proper aluminum or brass equivalents with o-rings and be done with it. (I don't know exactly which to recommend for your particular carbs.) Both the above re-use tactics bear some risk of failure and repeating disassembly/assembly, and really aren't worth the potential waste of time. Not to mention dumping gas on your engine and tire kinda sucks.
