Full disclosure: I have the Whisperlite Internationale, purchased in 1988, which uses a different pump than used today so there may not be the same issue with using alcohol..

Joshua Johnson I’m not sure about that chemical reaction. I am sure alcohol will displace water, water which would accelerate oxidation on reactive materials in the presence of heat. Anyway I had fun getting alcohol to burn in this stove. There is no way MSR would honor any warranty and I accept that fact. Be super cautious with mod it has good potential to be dangerous. Have fun!

Yes, alcohol with eaten out aluminum and also plastics. But I'm sure the plastic quality of MSR fuel-pump is the very hard one, it'll take decades for alcohol to eat the plastic pump out. Also one of the ways to anticipate this is to use the lacquered fuel-bottle, 1 good product is the fuel-bottle from Primus. One other thing about water, there will surely be some percentage of water left in the fuel-bottle, or in the fuel-line, or in the jet chamber. We can get rid of this small percentage of water by using petrol as a fuel for some longer time. It will flush the water out.

@@the_guardians_of_the_universe Yes , I totally forgot my alcohol inside of MSR fuel bottle . It's eat it up inside

@@maxinpains6937 yes, unless the aluminium fuel bottle's inside is lacquered. I need to learn how to lacquer the inside of an aluminium bottle. Primus Fuel bottle's inside is already lacquered, so it is safer to store alcohol inside.

So not the stove itself is affected but only the fuel bottle which is a lot less expensive when damaged. The reaction between alcohol and aluminum is very slow at room temperature. There wont be any contact between hot alcohol and aluminum, so i guess you just shouldn't store the alcohol in the aluminum bottle for extended periods of time. Considering all this, this seems not at all like a no go or big risk to me.

i got confused a midst of the instructions... how does the cut and bend part plays off? and where would that tube go?

@@itrstt66 just look at this to see what I meant: etrike.wordpress.com/2012/11/20/msr-whisperlight-alcohol-mod/ With the newer whisper Lite I think it's impossible to just slide the air control over the inlet holes, so you have to cut it open on one side and then bend it around.

I made a permanent one out of a piece of brass pipe. I had to sand the inside of the pipe to make it fit snug. Drilled two holes on each side the same size as the brass center piece holes. So I just line up the holes for normal use, and then I can twist the pipe to gradually close the holes if needed for alcohol. Otherwise its just a piece you don't even notice/use. ****do not attempt to adjust the air intake during use**** It will be very hot.. =)

@@scott1152 Can you post the emasures for that piece? and are you saying you use it with which jet?

@@itrstt66 Sorry, I was out of town.. Purchased a small piece of 5/8” brass pipe (internal diameter) from hardware store (12” long) You could also use copper pipe.. Marked the pipe for length (0.500”) but did not cut yet because I wanted to have the length while drilling the holes on both sides. Holes on each side pipe were drilled with (27/64”) drill bit (you could use a 7/16” bit). Then I cut pipe off to the (1/2”) length and started sanding a little on the inside to make it round so it would turn smoothly on the center piece of the stove. Also sanded down the outside just to make it less thick, but not necessary for function. Assembled the stove holding the pipe in-between the legs during assembly, and put the primer pan back on.. Pretty simple. If you have the access, you could weld a short piece of brass rod to turn it a little easier, and maybe during use to fine tune the flame, but also not necessary. For me the opening needed for alcohol is about 1/3 open (2/3 closed..). Internal diameter - .625” Height/Length - .500” Holes - .425” Thickness (not really relevant) .075"

Yeah but don't leave the alcohol in aluminum tank. It's gonna damage inside of the tank.

No sir I’m sorry to report that I did not try it with any other jets.

I've tried using the Kerosene and also Petrol jets, the alcohol was burning when in liquid form. But when it hot enough to heat alcohol into gas form, the flame went out, leaving only hissing sound and alcohol gas smells. I use 98% absolute alcohol and also in another moment I've used 96% Pure Grain Alcohol. The best alcohol I've found is 99.99% from Merck, it's anhydrous/dehydrated alcohol with very low toxicity, and also very low water composition.

All that I can say is: I did not have success burning alcohol until I drilled the UK jet.

Ohhh, thank you,, i just bought a msr stove, and i dont know if i can try burn it with alcohol

I’ve burned alcohol in a coleman apex stove and figured out how to make it run similar to camp fuel. Alcohol is a lot cleaner burning. ! I’ve done a similar mod to my whisperlite and now it burns alcohol just fine. Cool video.

I couldn’t make it happen. The flame just “spits” too much.

@@campinghack0675 thanks m8

darrendesilvavideo we can try going back and forth right here if that’s okay. What’s up? How can I be of service my man?

I want to know if I can pay you the for the service to modify my UK jet. I'm an American living overseas and finding the drill bit is difficult, and I don't have a drill press. I can source a spare from MSR USA, drop ship it to you, then you can USPS to my USA shipping forwarding address in NY. Thanks for the consideration.@@campinghack0675

darrendesilvavideo no problem. Send it to PO Box 757 Harrison Arkansas 72602. No cost to you as long as you agree to read the book of Matthew in the Bible.

Sorry, I didn't see this reply until now. I've read the book of Matthew and will read it again! It's been a while since the last time. Thanks, will organize it.@@campinghack0675

MSR is sending one your way for me. Great customer service. Thanks to you too! My forwarding address: Darren DeSilva 182-21 150th Avenue MCT 136071 Springfield Gardens, NY 11413 United States
