fuel leak

I have a 2002 grizzly 660 and recently I noticed what appears to be a fuel leak on the bottom of my motor. There appears to be a seal that looks cracked. Is this a sign of a bigger problem and is this seal easy to fix.

Im not sure, but did you turn your fuel off? I believe ive heard you should turn your fuel off or you could drain your tank. Could also be a stuck float letting fuel flow all the time, and maybe thats why your seeing a leak. Just throwing some ideas out.

Welcome to GC, nuts! You are sure to find help here as well as a lot of great conversation and humor.

My '02 660 did the same thing. It was leaking out of the overflow at the bottom of the carb. I had already gotten a carb rebuild kit and, after installing (and, of course, cleaning the carb), no more leak. If you have the overflow hose on the carb, you should be able to determine if this is the issue by simply seeing if the fuel is coming from this hose. The hose in question is attached to the carb at the dead center of the bottom of the bowl...basically, the lowest point on the carb. If you do not have a hose attached at this point, you need to order one...it has a one-way valve to keep the water out and it redirects any overflow safely away from the hot engine.
If it's not the overflow, check all over the carb for seal leaks and the hose from the tank to the carb. That pretty much rips the lid off of the fuel passage ways.

Grizzrider is right, you should shut off the fuel when not in use but, my shutoff valve leaks like a sieve (will be ordering new seals) and I would not be surprised if your did also...it's just one of those age things.

Where is this seal you believe to be cracked? Is it on the carb? If not, there may be more to look into than the fuel leak but checking it out will probably save you mare grief in the long run.

Another thing I might suggest is to check your wheel bearing seals, my rears are shot (more parts on order)
