Question about Buick Regal
It depends on where on the car it is leaking. For sure if it only leaks with the car on it is leaking from a gas line. There are rubber lines connecting the steel lines to the tankand they can go bad. The steel lines run up one side of the frame, usually the driver's side. They can also corrode and leak.
If you are quite sure the leak is on top of the tank then it has to come off. There are 2 straps holding it on and the bolts should be at the bumper end. Don't be surprised if they break off, they can be replaced.You will also have to unbolt the fill neck at the top because it will come down with the tank. Leave the cap on. You should block the tank up before you start and have a hydraulic jack so that once the straps are off you can slowly lower the tank with it. Make sure you have a piece of wood between the jack and the tank so you don't poke a hole in the tank. Gas as a liquid is not combustable but the vapors are so as long as you don't smoke or create a spark you should have nothing to worry about. That's why you use the wood blocks.
When you can see your problem you can get rubber gas lines by the foot and hose clamps at the autoparts store. If the steel lines are bad then steel brake line is an acceptable substitute and can be bought by length or by the foot. Hope this helps.
