Posted: Mon Jun 04, 2012 3:59 pm Post subject: Split Fuel Tap Rubber Piece |
|
|
Hi Guys!
after months of not driving my split , i have decided to completely service it so i have started removing the gas tank for old gas and rust removal .....
once i have removed the fuel tap , i have found that it was completely unuseable , no gas passed through it .
once i have disassembled it , i have found that it has a rubber piece inside , that was completely worn and out of shape .......
anyone knows a source for that rubber piece ??
the fuel tap is an almost NOS split unit with the 8mm pipe ....
any help will be greatly appreciated !
thank you

What rubber nowadays will work for this application? With various amounts of ethanol in the fuel these days, what rubber will withstand being immersed in fuel all the time?
Recommendations? |

That's a good question.
I once made one by using the old gasket as a pattern. I cut the holes using appropriately sized brass tubing that I had sharpened the ends. I put it in my drill press (without it running) and punched the holes.
I just used a large rubber washer I bought at the hardware store. Everything worked fine but when I eventually took the tap apart the rubber had swollen. _________________ Chris

I tested these rubber discs thoroughly before plunking down way more money that I will probably ever make selling them (the tooling costs were high). I soaked them in gasoline for nearly a week and checked for swelling. It was under 5% IIRC. And it really is not that much of an issue (5%) as the disc is entirely captive in the seal on all sides.
Buna-N rubber was used I think, known for its petroleum product and oil resistance. It is the same rubber that is used in rubber fuel line hose. _________________ John Henry

I think I remember seeing some cork ones at one point long ago. But I really don't see that working well at all.
I have a few NOS ones. Old black rubber, as stiff as plastic now... _________________ John Henry

If you make your own, VITON gasket material is the way to go. It is impervious to gas/oil/diesel/gas additives and does not swell. _________________ Currenlty Corralled:
