    Look what i found in my fuel line.

    My 1999 250 EFI started to stall when throttling up. So I started my troubleshooting. When I got down to the fuel line I started to blow compressed air through it and it wouldn't go easily. I eventually got to a hard part of the hose and opened it up. Surprise! This is what I saw.....
