One piece VM fuel rail leak repair

[raistian77]

My 79 850 has the VM carbs on it with the single piece fuel rail. Instead of O'rings this one has bumps that are supposed to act the same. According to my dealer these lines are discontinued. When I did the original strip and dip I lightly oiled them during instalation. On the first run up they leaked. Retore them down and cleaned them. Used a small amount of Indian Gasket shellac and let it tack up. Reinstalled with no leaks

nicely done, surprising what a bit of ingenuity can do.

I had a minor leak on one of the sleeves too after my carb rebuild. I was just about to remove the carbs, but ran out of time/enthusiasim that evening. When I returned to do it the next morning, the fuel had swelled the joint and had stopped leaking. I haven't had a problem since (17,000 kms ago).

Anytime those leak, just let them leak. They swell up and stop leaking in a few hours.

I think they must have made them out of some kind of swelly rubber stuff on purpose.

The few times I have had them leak, I just put a couple wraps of Teflon tape on them.

good catch, my local dealer had nothing to help on that problem.

I let them sit in gas for a few days, then put those O-rings on the ends anyways seemed to have stopped my leaks

4 years ago, I bought all new for my '80 850G. It was spendy.

Good ideas, all.
