03 yz450 new 3.3gl tank leak

8 posts in this topic

Shortly after putting a new 3.3gl tank on my 03 yz450 I noticed fuel coming out of the bottom hose on carb. Pretty steady stream whether running or engine off. Any suggestions?

Remove your float needle and polish it, and the cavity, and re-install.  It is sticking or leaking.

 

Inspect the needle tip for grooves and the seat for pits. If you see anything, replace them.
