I have a 91 4x4 22re that started leaking gas from somewhere on top of the tank. I finally got the bed off and noticed that the cap on top of the tank (over fuel pump) is somewhat rusty looking, as are the lines that come out of it. Do I have to replace the entire cap or does it normally look this way? The rest of the tank looks good and the truck has been sitting for a while so I doubt it will start to check for the exact location of the leak. Also are those lines under pressure coming out of the cap or can I just take the cap off to check for leaks etc...
Thanks for any input, first time dealing with this type of issue..
