The fuel on/off/res selector is leaking on my 06 trail boss. I replaced the fuel filter and got to looking at the shut off and noticed that if I push in on the slector **** it leaks gas. Is there something I can tighten up or do I need to replace the valve.

 

there is a gasket inbetween the valve and the tank. are you sure its not coming from that? its just a cork gasket IFAIK. you could try tighten up the two screwes for the valve or take the vavle out and put some permatex on it.
