Ok the search is over I finnaly got me a truck, it is a 1997 2500 4x4, I have a problem when I went to fill it up today I noticed that it was leaking but only when the diesel was being pumped into the gas tank. Is this a quick fix or do I need to put all new lines in?

 

Check the fill hose from the side of the bed to the tank.

If it isn't leaking except when you are putting in fuel, it is either split or loose.

 

Now that it you have a diesel it is no longer a "gas" tank.

 

ya I know brain fart.
