[QUOTE="TimberTim, post: 439195, member: 20208"] My Smog Tech told me he smelled gas at the rear of my TJ when he pressurized the Gas Tank and I should check the rear area for leaks. Another way to pressurize your tank is to use your Rubber Vent Hose. Disconnect your vent hose where it connects to the Steel tube that runs down the frame by the rear Drivers side Tire. There are three rubber Hoses that connect there from the Tank the two bigger hoses are the Supply and return, the smaller one is the vent hose and the one you want, Connect your afore mentioned customized Tire Valve Stem to the vent hose by means of hose adapters. you only need to interduce 4 or 5 lbs. of pressure into the tank ( don't go crazy here) more is not better. spray soapy water on the top of the tank and watch for bubbles. Doing it this way will also test your Gas Cap. after 3 or 4 minuets remove your gas cap and listen for a Hiss of pressure leaving the tank, if no Hiss is heard keep pressurizing and spraying soapy water and looking for the leak. When you interduce air pressure into your Gas Tank you can see it bulge like a balloon. Try this at you own Risk, I accept no responsibility for that one SILLY GOOSE out there...... [/QUOTE]
