So I have been using the Heater buddy hose for a few years to hook my Coleman Road Trip Grill to a larger 20lb cylinder. But that meant I either needed to bring separate cylinder (which I always forgot) or hook up to the second cylinder up front. Now I use one tank at a time so when one runs out I know (do not use the auto switch).
This weekend I ran out of propane in the first tank and thought... I've been using the second tank for the last year for the grill, how much propane is in it? So that was it... It was time to make the switch to use the built in quick connect. BUT, I still want to be able to use the smaller 1lb cylinders to keep things portable. It was actually pretty easy, cost about $50 with everything had on Amazon.

I had two options, use the one regulator or buy a second. I opted for using the original regulator to save the need to carry extra stuff. All the threads on the Coleman regulators are proprietary so I have been told. EXCEPT for the threads on the connection at the brass end to the chromed steel tube. It is 1/8" NPT. The quick connects are 1/4" NPT so this is why the need for the bushings and fittings from 1/8 to 1/4.
Disassemble of the regulator was pretty easy. It has VERY small wrench slots but none of my wrenches would grab the slots so I used a pair of needle nose Vise Grips.
**There is a little check valve in there with a spring when it is unscrewed so keep a hand on it. **
I did not reinstall the check valve, it is there to keep the regulator closed if it is unscrewed from the grill with a propane tank installed. The new set up uses a 1/4 turn valve for the one off as you will see. But I will keep it just in case.
Once the regulator was taken apart it was just a matter of putting all the fittings together how I wanted them. All connection are wrapped in yellow GAS tape, not the white Teflon stuff... On a side note, I actually only ordered one roll and they send a pack of 12 for the price of one... Not sure what I will do with 11 extra rolls!
I do have the regulator put together this way for a reason, if the small bottle is used it still faces the same direction it had when stock. What I an referring to is the 1/4" 90 at the female quick connect. It is FACING and parallel to the Coleman regulator tank opening. It also allows the metal hook (used to support the bottle) on the grill to help hold the weight of the new regulator setup and weight of the bottle still. It is a bot tough to see but in the last photo with the bottle in it you can see the hook supporting the setup.
Last thing check for leaks and go grill something! I have read there will be a slight loss of pressure (aka BTU's) by doing this as Coleman claims they allow MORE gas pressure than the low pressure regulator on a trailer does. I dunno, mine would get 600 with the stock setup so I can live with a loss of a few BTU's. I tested the grill in the yard and everything worked great. This weekend it will get a test at Hershey so I will report back.
Any questions let me know! ENJOY!
