I could use some help. I recently bought an 2005 R1200RT. It needs some TLC. I kept smelling fuel. I took off all the plastic around the tank thinking it was the quick disconnects. But they are fine. I see no fuel dripping anywhere. I believe there is something wrong with the filler neck/cap. It doesn't seem to seal off at all. I took it off the tank and every thing appears to be there. But the cap doesn't go down far enough to touch the tank filler tube thingy. The vapors are just coming out around the cap. It looks to be at least a quarter on an inch between the rubber gasket on the lid and the filler neck. What could be wrong here.
