Dan and 2-Ply,

Do you guys have any problems with those MSR bottles building up pressure if they are in the sun...or on a hot day?

Or do you fill them up to the top so they have no vapor space?

I have a lead on a bunch of bottles, well a few anyways, in the back storage area of a Army Navy store.

I've never tested them in the sun, but for the last 35 years, they've held up with no leaks or disasters.

I fill them to within 1" of the top. The gas does expand and builds pressure, so a little care or later releasing the pressure is not a bad thing. I would definitely leave some air space for expansion.

I have one of the really old ones that now has a rounded bottom and will not stand up well. Looks like the bottom expanded with pressure and acted as a safety margin. Don't know if that was a planned feature or not. These are meant as fuel containers for hikers and with elevation changes a common thing and the danger of gas on skin from a leak in a back pack, I think there might be extra safety designed into these containers.

I know I would not trust any other container as I have had some bad experiences (but lucky) with other containers and with strapping containers to the bike. And I see others assuming the same things I did in my early years.. I survived the mistakes, I was lucky.

Thanks 2Ply...

Yeah no problem at all. I keep mine in a foam lined gun case so they don't roll around the truck but they never leak. Much better then the plastic gas can that would build up pressure and "relieve" itself all over the truck. The MSR cans are made to hold fuel so they are spec'd for the type of pressure gas reaches at normal temperatures when camping in the arctic or the desert. Get them, you'll be happy with them.

Also makes fueling much nicer during an event not having to balance a 35lb fuel can when your back muscles are fatigued.

Plus everyone thinks you've concocted some super secret jumpjuice formula.

How true!! I forgot that feature. Recently, I bought an intermediate transfer plastic gas "can" that has a push button valve in the spout with the vent at the nozzle. This maks filling the bottles a real snap.. When the 'gurggling' sound stops, the gas has reached the vent and I can then let go of the button and the fuel bottle is perfectly filled with one inch of air space. If you don't know what I'm talking about, I'll post a photo later.

:smirk: :thumbsup: "Psyche-Out" at a Trials Event was one of the secret weapons of a couple of the top guys... Anything to keep the competition guessing.. Or when a key rider is at the start waiting for the signal and you make a big OOPS and pretend to slip on something in the section :smirk: Or maybe look closely at his tire or chain and start to say something but then say Oh, never mind and walk away.. :busted: Dirty little tricks like that, but loads of fun among friends. :thumbsup:
