I am having a gas related issue and wanted to see if I could get any pointers on what to do about this before taking it into the dealer (which I don't mind if I have to since it's worth it to have it fixed). The other day I had my blazer in the garage just to do some general maintenance on the new rims (checking lug torque and cleaning) and heard a splash all of a sudden - like a drip. Gas was dripping out the back end. I looked back there and there was gas leaking out of this black module, which I have never seen before. I disconnected the hose and 1 harness and brought the little "valve" to the dealer. They told me it was a EVAP Purge Valve and had one for me for $22. Even though I didn't know if that was the problem, I figured what the hell, only $22 so maybe I'd get lucky. However, this didn't make a difference.

Any idea on what else I could check myself before bringing it into the shop? There is a harness that plugs into this valvle. One wire is definately a ground, and the other does not have constant power, which I assumed to be due to the fact that it was fed in from some other sensor or relay.

I appreciate any help on this. I will be working on this all weekend before leaving to LA for work on Tuesday. Thanks again!
