Okay this one may be a little odd.... but I've just bought the MSR burner for my Trangia - which by the way is simply amazing - but I'm having a problem working out if I should keep fuel in the fuel bottle with the pump or not....

Here's the text from the instructions

"When the stove is not in use, fuel is carried in the fuel bottle with the pump fitted (air pressure released) and the burner dsconnected. (all straight forward so far... but then) Store the pump in an empty fuel bottle."

I have a separate 1lt fuel bottle, but also have of course the 0.5lt bottle with the pump, now all I'm trying to work out is if I can leave the fuel in the bottle after I'm finished cooking and I've released the pressure - as there's now way to disconnect the pump from the bottle, and I'm certainly not going to be carrying around an empty bottle - what does all this mean.

Confused of Hatfield.

Hm..

So when you say..
Do you mean that you have an MSR burner (like the DragonFly), and you're using it with Trangia saucepans and stuff?? I'll assume that's what you mean, but if that's not the case, then disregard the rest of what I'm saying here as meaningless verbal scutter.

My MSR has a 1L bottle, and then the pump attaches into that. There is also a separate screw stopper for the same 1L bottle, so you could store the fuel in the bottle by detaching the pump, and using the stopper, or with the pump in place in the bottle (valves closed, pressure released). I normally start my trip with fuel in the bottle, and with the stopper in place. At that stage, the pump is stored with the rest of the kitchen stuff. Once I put the pump in place in the bottle however, I tend to leave it in place after use, cos onces it's stinking of petrol, I don't want to be trying to store it with other stuff. I take the burner and store it separately alright.

What do you mean when you say...
On my MSR, the pump can be connected and disconnected from the 1L bottle.. maybe it's just getting caught when you try to detach it?? Are we talking about the same product here?? Note that I only have one bottle, rather than 2.. Maybe the 2 bottles are complicating the issue.

I keep the fuel in the bottle with the pump, with pressure. The manual says this is bad, I think, I never actually read it...

I use the half litre bottle with pump attached and after use, release the pressure and store it. I also carry a 1lt MRS bottle as a backup. No problems so far.

I've found that petrol makes everything very sooty and it's a bitch to clean; so I'm going back to using white spirits (Shellite).

I carry another 1lt MSR bottle full of petrol also (just in case I run our of gas for the bike or fuel for the stove).

Ahh cool that's put my mind at rest a little - I think I'll go ahead and keep the fuel in there with the pump...

It's the MSR attachment for the Trangia system :-)

As above, I too store my dragonfly pump in its bottle sometimes with fuel sometimes without. But the seals can get dry and need oiling now and then. If you dont the seal will become detached from the plunger and usually right at the bottom of the cylinder. Happened to me a few times. But in the spares kit with most msr stoves you will find a safety pin, undo it, bend about 2mm of the end to a 90 degree bend and use whalla.. seal retrieval tool. Dont worry the only other use i have found for this large safety pin is as a pricker to clear the deisel injector on the stove, when not using petrol. Which i have only done once.

Only really had this problem when stove has been unused for a few months or longer. The older/earlier pump seals suffered more, as they did slowly degrade if in contact with petrol. The new ones are a bit more durable i am told by MSR uk importer.

Also if you own an msr stove you can have them serviced/inspected by the uk distributor for a nominal fee of (was £15).. takes a couple of weeks and they replace any minor stuff like seals/wicks etc and sometime major stuff, though they may charge cost of parts if its a big bit.

If anyone needs the details, pm/email me and i will dig them out and pass them on.

throw us into the gruop. we always kep the pummp in the bottle and just relieve the pressure. I made a fairly stiff leather "box" for mine and leave the stove hooked up. bear in mind that you really have to disguise the bottle if you go on a plane. It cannot be legally flown. they confiscated my bottle at heathrow in '92 --leaving. solution. next trip in 94'-- buy an MSR water bottle and use it. they are made with the same thread and size. also learned that in UK they won't let you put fuel into any thing other than a container designed for fuel. solution is to buy a big bottle of model paint ( I had to settle for two bottles of red nail polish) and paint the thing red. then before getting to the airport use a remover to get the paint (nail polish) of and it is your water bottle. Back then you could carry a water bottle onto a plane. These days you can't even take toothpaste or a thermos of coffee.
