Here's how to remove a pump tube from a stove in case your NRV is so stuck you just can't get it out.

2022 Update - Torches!
In the video I’m using this torch:

I also commonly use these two torches and you can see me using them in my other videos:

2019 Update - Thread Sizes! If you want to clean or "chase" the threads on the pump tube end block like I show in the video, use a M8 x 0.75 tap. 5/16" x 36tpi and 5/16" x 32tpi are approximate American taps sizes that will work but won't be as accurate as the M8 x 0.75 thread tap. BONUS! The barrel of the NRV is threaded M6 x 0.75. *All* these taps require ordering from specialty tool and die guys. I like to use Victor Machinery, victornet.com but I think they have a minimum order size. Get a die(s) to match your tap and some other items and you're all set.
2018 Update - "BernieDawg Bonus Repair Tip":
When doing any soldering repair on a kerosene fueled stove, the kerosene is your enemy. Kerosene is a penetrating oil! Even the slightest residue of kerosene will inhibit solder bonding and flow. If your stove is leaking fuel somewhere, drain all kerosene out of it, flush the tank with acetone and drain. Then, fill the tank with acetone and pump up the stove so acetone flows out your leaky place for a while. This will flush kerosene residues from the location of the leak so that kerosene residue won't flow out and mess up your soldering to come.
