" I cannot help you unless you have a Yamaha part number", he said. What the heck? I remember when the parts guy was the smartest guy in the shop and could find anything. I guess not anymore! I ended up getting some Stat-O-Seals through work. These are like o-rings cast into a metal washer. They fit very tightly around the threaded part of the taps and the metal part keeps the rubber from squishing out when you tighten them.My next problem was that the new taps would not screw into the tank.
Upon examination, I found that the threads were malformed at the end, plus there was a lot of plating on them. I really did not want to send them back since i took me two weeks to get them in the first place. So, I thought I would fix them with a file. After a half an hour of careful filing, I got one of the taps to screw in about two threads. Enough of that! There was no way I was going to risk damaging the threads on the gas tank. I ended up taking the rubber seals out of the new taps and putting them in the old taps. Not the most economical solution! The old taps with the Stat-O-Seals screwed right into the tank. Of course, they don't line up. And doubling them up doesn't help since they are about 1 mm thick, same as the pitch. I may have to make some shims at a later time. I have not tried putting the gas back in yet. I figured if it leaks, it would put me over the edge. I will test it later.Pete
