Help! The pickup tube inside my gas tank has become clogged with crud. I would guess that he screen or filter on the end is plugged up tight. I attempted to drop the tank this weekend, but only managed to move one of the strap bolts one half inch in 3 hours. The other one is fused on tight. Any hints as to how to get this tank off? Is it advisable to cut the straps and find replacements.... or should I just keep working on the strap bolts?
