So the very first day I owned my XTZ I filled it up and gas started running out from under it. As I looked closer there's a filler tube extension that leaked the fuel. So I over filled it a little no big deal. Correct me if I'm wrong but if I was to go through water that would reach that seem wouldn't my gas tank fill up with water? Are all Prowlers like this and is it a problem if I went through water that just barely goes over my gas cap? Any ideas or is this not a concern? Thanks! KO.
