gas valve

Having done this it is a relatively simple process to remove the screw and replace the O ring when it next begins to leak, which is inevitable. Even if you replace the valve with a new one, it will probably again leak within 6 to 18 months. You will then be faced with the same problem that you now have.

If you have the lever type valve, the only solution is to replace the valve with a new one. Again, within 6 to 18 months it is very likely that it will either begin to leak around the stem, fail to shut off, or both.

The fuel shut off valve with the screw is a piece of doggie do. I do not know how they can sell those things for 40+ dollars and look at their self in the mirror. Rebuild yours and save your money.

Look on the bottom of the valve and you will see a brass drift pin. This pin holds the shut off screw from coming all the way out. You can try prying it out with a knife but that may or may not work.

What I did was to grind the head off the pin so I could see the actual size of the pin. I then drilled out the pin with the correct size drill bit. Once you get the pin out you can back the shut off screw out all the way. You will see a slot on the screw where the pin fits into. There will also be a o-ring on the end of the screw. Replace this o-ring with a new one. Make sure the o-ring is fat enough to protrude out from the screw a little so it can seal. Install the shut off screw back in the valve and put it at about half way from closed to open. This will line up the pin slot with the pin hole. I used a #12 screw in place of the drift pin. You want it long enough that it fits in the shut off screw slot but does not touch the screw. I used washers to adjust the length of the #12 screw.

If it ever starts to leak again you just take out the #12 screw and back the shut off screw out and replace the o-ring again. Total cost is less than $1.00 for the #12 screw and a o-ring.

I think someone posted that they added a ball valve post tank valve and brazed the tank valve together in the open position. Kind of extreme, I know, but I think it worked!

Hope this helped.
