I have a 86 camaro with a fuel leak on the pipes that come from the fuel tank, it's no where near as bad as it was but a leakage is still evident. What I was wondering was is it possible to "carefully" cut an access hole in from the rear above the tank to see if the problem can be rectified, or do I have to drop the rear end. Any help again would be appreciated. Many thanks Kev

 

Well you could cut the floor. BUT I, and everyone else on the board would say don't do it.

Drop the rear axle and replace the top fuel lines. I removed and reinstalled my tank without dropping the rear axle, but if you can drop the rear axle its a lot easier.

First start the car, and look underneath, crawl under if you have to. The fuel could be spraying out from a place where you could get in and replace the lines without dropping the tank.

 

Good evening from the uk. Firstly the one of the fuel lines, I think it's the one that delivers the fuel to the engine, had badly corroded. I took as much of the bad pipe away and replaced it with a rubber substitute. This in turn worked, but it started to dribble down the outside of the rubber pipe even though I took care in fitting clips very carfully as not to crimp the pipe. When Upon first inspection the pipes at the top of the tank, what I mean by this is when lying under the car putting your arm as far as it will go along the fuel pipes, which I presume is where the pipes leave the tank. They feel lose, but the leak doesn't seem to be coming from there, but as usual I may be wrong.

 

If there is a drizzle around the rubber pipes, it may just be in need of a clamp replace.

But from what you said, it sounds like you have spouted a leak from ontop of the tank. I would try to refit the rubber hoses with new clamps first. If you still smell fuel, then I would go ahead with removing the tank.
