BikerGril, you can do it. Once you get the replacement regulator be sure the hose connection locations are in about the same place and orentation. Also check any mounting hole locations to insure it will mount the same way. If that is a go, turn off the gas at the tank valve, go inside and turn on the stove for a few seconds to bleed off the gas in the lines. With that done using a box end or liine wrench remove the line from the tank valve to the regulator, then remove the out line to the rig. After you have removed the inlet and outlet hoses then remove any mounting bolts and remove the regulator. Install the new regulator. Using and old tooth brush or brass brush remove any old tape or compond from the tread area of the inlet and outlet hoses. Apply a thin coat of propane approved pipe "dope" it will be in the gas/plumbing section of the big box stores. It will look like a small tube of tooth paste (the tube is usally yellow, the white tube is usally for water/air lines. Just ask the dept guy, he can help you find it. Back to the project. Besure you do not get any of the pipe dope in the end of the fittings, just on the threads. Ok now screw the fittings into the regulator and snug them up good with a wrench. Now "slowly crack" the valve open a little to charge the system. After about 10 seconds open the valve all the way. Using a spray bottle with a cup of water and 2 or 3 drops of liquid dish soap mixed, spray some on the fittings. If it is leaking you will see bubbles forming. Keep in mind that you will have a little sudsing, but you will be looking for actual bubbles forming. If you have a leak, snug the fitting with the wrench a little more and repeat until no leaking. Also you will need to go in and light the stove to bleed any remaining air from the lines. It may take a few seconds for the gas to get to the stove before it will light. Once all this is done, kick back with a cool beverage of your choice and relax and think about all the money you saved. Hope this helps you out.
