Worked great
Worked great for my 08 harley. Was able to stop my fuel leak. Fit just right. Not to hard to do either. Good price if you can do it yourself.

I needed to pull the tank, and years of experience tells me when you have to pull your bike apart, that's the time to replace any relatively cheep parts that have a tendency to go bad. O-rings and gaskets are a perfect example of that. Your petcock has 2 O-rings and the line has 1. I would recommend buying this kit and an extra set of O-rings that include the small one for the line. I also recommend, when you install the new O-rings in the petcock, you install the lower (largest ring) first. This is so the deeper (inner most small ring) does not have to pass over the empty groove and risk barfing it up. So.... this lets it slip past the first groove with no risk of damage. A tiny bit of grease or oil helps the rings cooperate.

Klappt nur bei neuen Ventildichtungen .
Kauf lohnt nicht . Die meisten dichtringe sind ausgehärtet und lassen sich nicht lösen (hart wie stein) . Es muss 90 % das ganze ventil Neu . Sorry.
