Broken pipe underneath BBQ, need repair advice

You need an EZ out to remove the broken piece in the regulator and then a pipe die to rethread the pipe, looks like a 1/8" pipe

Could use an Easy Out to remove the threads in the regulator and re-thread the pipe.

Use Google. Type the name of the grill and model. I've replaced parts for my tents to grills no problem from stores that focus solely on that stuff.

If you can tell me the model number I'll try to find a supplier for new parts. If parts are not available you might try this if you have access to a shop. See if you can get the broken pipe end out of the regulator by using a large easy out or internal pipe wrench. If you get it out then you can have the burner pipe re-threaded on the broken end and probably just move the regulator bracket over a bit. It looks like it is just attached by screws. You will probably have to grind a bit from the case so that the hole is aligned. Another option would be to cut a little off the broken pipe and have a nipple welded back onto the pipe.

Try Coleman. I have repaired many Coleman products and repair parts are pretty readily available.

All of the above is really good advice. One more try would be to contact the folks who install gas logs in fireplaces. They should be able to fix this in a couple of minutes.

I'd bet there's sealant on the threads of that stub in the regulator housing. If they used the type that requires heat to release, be careful since some of your reg parts may not enjoy being hot.

If the sealant is a hardening type paste it can be very difficult to break loose. If you heat it up you will probably ruin the seat or diaphragm. You can try drilling out the pipe with a bit a little larger than the inside diameter so it is almost cut through to the threads. Then use a sharp punch and try to bend it inward in several places, then try tapping it out counterclockwise. Worst case, you screw it up and buy a new one anyway.
