Help! Every time I fill the tank up I get a major gas smell in the cab. You really can't drive it because the gas smell is so bad. I replaced the rubber grommet on the filler neck and also checked the gasket on the sending unit, which was fine. It looks like there is some gas residue on the area where the neck goes into the tank and there is a strong gas smell there also. Any suggestions?? Is it time to replace the tank?
