Read the Stant cap has problems, with no locking door on the 5G, anybody found a locking gas cap for the new (July 2010) 5G? I know gas cannot be siphoned, but stuff can be put in the tank.
What a nightmare the $%$^ gas cap does not come off at all. Plastic junk is permanently clicked in. No it is not a locking gas cap it is the cap that came with the 2004 4runner. I have to drill it off.
Massively bad engineering. Suddenly I hate my 4runner.
