Gas Leak
I just bought a 1997 Blazer 2 door and there seems to be a small leak around the gas tank. It also only appears to happen when you turn the truck off, so I'm guessing that it may be a fuel line. What do you guys think I should take a look at? I'm not familiar with Chevy's I'm more of a Jeep guy.

First you should make sure that it isnt leaking all the time which would be a sign its a tank leak. If it stops after awhile it it most likely one of the fuel lines if they look anything like mine do then it wouldnt take much to pop a hole in them.

The fuel pressure line is 3/8" and the return is 5/16", the vapor line could be 1/4" or 5/16". Dorman makes fuel line repair kits and most auto parts stores carry them. Cut out the bad section with a tubing cutter and match it up at the auto parts store. The new line connects to the existing line with a compression fitting. The worst part of the job is getting to where it's leaking, might have to drop the fuel tank etc.
