I bought my MSR-XGK in Spokane in 1978. Killer stove. The older stvoes actually put out more heat that the newer models.

Old vs new for heat output. "The new model is thus about 6% slower. "

I have one of those military ones. I picked it up last year on sale. I've got a maintenance kit coming mostly for the white gas jet for now. Anybody know what the deal is on the Arctic pump? I ordered one because I plan on this being a winter stove(melting snow). Seems odd the military version doesn't have it but maybe it only is needed with white gas. Thanks . standing by.

I used my XGK II down around or below -50F without problems.

https://www.msrgear.com/stoves/arctic-fuel-pump

From MSR: Specifically engineered for use in temperatures below freezing, our Arctic Fuel Pump features extra-robust seals to prevent leaks in arctic conditions. It is field-maintainable and works with all MSR liquid-fuel stoves, except the Dragonfly® stove. Use only below 0° C (32°F).

From the Classic Camp Stoves forum https://classiccampstoves.com/threads/m ... ump.34589/

MSR did make a service kit for the Norwegian Army that included the blue seal and ditto o-rings. I recently got hold of - and just passed on to a domestic scout group, some kits that were left over from a major procurement by the NA. As a curiosity, I had them listed on ebay for almost a week at a very reasonable price (compaired to the std kit) with no interest at all.

In principle these seals and o-rings should be available from MSR. The reason for not using the blue seals in temp above 0C is that they then will wear more rapidly.

In the video the narrator said that the AV gas jet was good for white gas. Can you compare the XJ jet to the new one? (GK?)


Thread on standard jets at ClassicCampStove: https://classiccampstoves.com/threads/m ... ion.14523/

I will edit this jet list as I compile more info

GK is a “compromise” jet suitable for both White Gas/Coleman/Naptha and kerosene/paraffin/lamp oil/mineral oil.

XGK-EX X-Jet 419267. Diesel
XGK-EX Shaker GK-Jet 417206. Jet for Gasoline and Kerosene (petrol and paraffin if you are a Brit). This is the model with the flexible fuel pipe.
XGK-EX GK-Jet 419266. Jet for Gasoline and Kerosene (petrol and paraffin if you are a Brit).
XGK-EX Shaker X-Jet 417228. Jet for Diesel, this is the XXGK model with the flexible fuel pipe.
XGK G-Jet Non-Shaker 419250 Petrol Jet for older non-shaker jet models.
XGK K-Jet Non-Shaker 419251 Paraffin Jet for older non-shaker jet models

Military
XJ for JP-8
XG for Diesel

XGK II Shaker Jet Models have a letter S prefix: SG and SK

This is what my XGK shaker jet stove looks like and mine was heavily used. I think I bought it in the 80's or 90's. It became pretty beat and needs a rebuild.

I bought a commercial XGK EX a while back and later came into a XGK EX military with a number of the tan bottles.

The XGK in its various forms is a bullet proof stove.

While it will burn just about any petroleum based fuel, in extreme cold weather conditions the best performing fuel in my experience is white gas/ naphtha. White gas/ naphtha is also the best general use fuel.

While it will burn other fuels, the use of other fuels may require the use of Firepaste or similar products (alcohol based hand sanitizer for example) to preheat the fuel so that it vaporizes. The stove has a wick at the bottom of the burner cup which normally does this but supplementing the wick with additional accelerants helps to get fuels like kerosene and diesel to vaporize by heating the stove body up so that the fuel vaporizes before going through the jet. Frequent flameouts can occur if you are not careful and high pressure liquid fuel spraying around is a significant safety concern...

Thanks! I have only ever used white gas in my XGK when in the US but I guess I should give some other fuels a try in order to have some hands-on experience with them before the need arises.

Using my XGK II a long time ago at 17,000 feet. You can spot the red MSR fuel bottle and the pot in between our tents. The stove was in constant use and performed flawlessly while melting snow and boiling water.

Are these the same as the MSR Firefly (or rather is the Firefly the same as these)? They look the same, the firefly seems to have bigger stand though.

I think the MSR Firefly has evolved into the MSR DragonFly

Apparently it might have a unique pump and it does have dual fuel valves for flame control which helps for more specialized cooking and even baking. The XGK fuel valve is a little coarse for someone who wants fine flame control. The flame spreader design looks the same but the DragonFLy appears to be bulkier than the XGK

DragonFly specs

Fuel Diesel, Auto, White Gas, Jet, Kerosene
Burn Time (Max Flame) (20 oz. of fuel) (White gas) 2 hrs. 6 min. / (kerosene) 2 hrs. 33 min.
Average Boil Time (White gas) 3 min. 30 sec. / (kerosene) 3 min. 54 sec.
Dimensions 6.3 x 5 x 3.5 inches
Weight (Stove and pump only) 14 ounces

XGK specs
Dimensions 5 x 3.9 x 3.5 inches
Fuel White Gas, Diesel, Auto, Kerosene, jet fuel
Burn Time (Max Flame) (20 oz. of fuel) (White gas) 1 hrs. 49 min. / (kerosene) 1 hrs. 38 min.
Average Boil Time (White gas) 3 min. 30 sec. / (kerosene) 2 min. 48 sec.
Weight 13.2 ounces

Yes you are correct! Thanks, my memory clearly not working.

You are most welcome! Sometime soon I will pull my XGKs into one spot to compare some things. I may disassemble the oldest one and clean it up.
