I have an 84' BJ42 and I replaced the fuel tank last year. If I recall correctly there are at least 4 smaller hoses that run to the tank besides the main fuel line and filler hose. these lines run to various places on the tank itself. If you remove the side panels next to the filler neck (if your year has them) you will see a plastic vapor gismo that has most of the hoses that run from the tank. You sould have two that run toward the engin, one is main fuel and I think there is another that is the fuel return line.Caveman said:So are all those fuel lines really necessary? Especially the one that loops across to the left side, under the rear deck,floor? I'm not exactly sure but I think it is some sort of emissions equipment.
