fuel valve

It has proved near impossible to find a fuel petcock for my 81 xs400 that is in working order. Do you have any suggestions for a bolt on aftermarket one? :banghead:

Hello everyone, as i was cleaning every tiny bit of my fuel valve i accidentally ripped of the membrane in it. i noticed how it was glued on one side. ofcourse i tried reassembling it without gluing it back together but with a leak as a result. i have searched this thread ...

I took off my tank after draining it to make sure it was clean. removed and cleaned the shutoff and when I was shaking the tank I could feel and hear something in there, I tipped it upside down with my finger in her:wink2: and found this filter thing, obviously it goes in the top of the shutoff...
