I have an 85 K100RS, and the petrol sending unit works, but the cap that screws into the tank broke, and is leaking gas. I will take a picture, but basically, the bottom blew out under the pressure against the tank. See this link for the type of sending unit i have https://sep.yimg.com/ca/I/yhst-15102260216258_2269_118626600
It is discontinued so i am having trouble finding a replacement, not to mention they are over $100 USD where they are listed. I'm wondering is anyone has run into this, and come up with a fix. As mentioned, the part 'works' but leaks gas. I've tried the QuickSteel tank repair kit, designed for plastic gas tanks. it held for a couple days, then failed. I tried epoxy before that, but it failed. My problem now is, what started as a crack in a half circle around the bottom, has spread, then spread again, and now the whole bottom broke off. I will say, it was a clean break, in a circle, around the bottom, so i think i can repair it. Just curious if there are any products people have used, or good solutions someone has come up with.
The only other solution i'm contemplating, is having a machine shop make a new cap out of metal with a hole in the bottom for my probe part, and see if i can sandwich that in with two o rings to make it work.
