hey guys,i have a 3710 GST with 800 hr on it that's leaking fuel under the tank area,dripping off bottom of trans ,about 2 cups in 24 hrs,the fuel line is fine coming off the bottom of the tank ,cant see any other fuel lines in this area,i thinkin the tank could have a leak, i never let my tank get low so I don't think its a rust issue,any help would be great

this is just a SWAG....

there should be a return line coming back into the tank? If so - there could be problem there, does it leak that much sitting still? Or only running?

Either way - clean the area with brake cleaner and look with flashlight and see if/where leak is occurring.

Look at the top front of the tank there will be 2 return lines.

The other option is that you have a failure of the out line on the bottom of the tank.

if you need up close pics to see one out of the machine, let me know. I have one out right now I could take pics of.
