My pilot wouldn’t stay lit on my Mr.buddy heater , ordered this and installed it and it fixed the issue and works great now . I will say it’s not an easy install, the little heaters are hard to get apart and put back together.

Just transfer the thermocouple and igniter to your old mounting plate with the original pilot jet. The replacement is way too big and the pilot flame was 6-8 inches.

I got dirt/dust in my polit line, and it would not stay lite. Tried to blow, shake and even tried a fine wire to clear, nope. Finally, I purchase this replacement item and in about 10-15 minutes my heater was back up and running. I purchase a 5-foot hose without a filter and that I believe caused the dirt/dust issue. Now I have a 5-foot hose with filter, and I hope it will last years and years without a issue.
