I paid $75 for a local shop to pump smoke into my Cadillac, so I'd say that price is fair. It's not rocket science....pump smoke, see where it comes out. Even LeBron James could figure it out.

You should use coal, although make sure you use soft (bituminous) coal cuz hard coal (anthracite) doesn't smoke. Jack the car way up and spread motor oil, kerosene, or whatever you have around that's flammable under the car, put the coal in the middle directly under the gas tank and torch it.

Or maybe an easier way: Search the forum for Dano523s (?) post about how to test the valve. But after getting it out it might be just as easy to replace it for $30-40 or whatever a new OEM is.
