MSR Dragonfly fuel line replacement

I took the Dragonfly apart the other day to see what the fuel line was like inside that braid.

Today I picked up some replacement Gates fuel line.  This particular example is a rubber line with internal nylon braid, rated for 50psi with fuel.  I looked for the specs on the pressure the MSR hand pump can generate but found none;  I’d guess 2-3psi.

The issue here isn’t pressure, but  Continue reading “MSR Dragonfly fuel line replacement”

slight repositioning

Muffin and I were on a walk last evening and found a superior spot up the trail a bit.


  1. further off a “main” established trail
  2. allows me to orient the van differently — I prefer E-W orintation but I could only fit in N-S in the other spot while staying off fresh flora
  3. cool rocks
  4. tree canopies a bit higher – I was bumping into limbs before



  1. up against a hill on the east so I’m getting usuable solar power about 45mins later (0820) than before (0745).   Still achieving Vabs around the same time (1030) because of the generous paneling.

There’s also a bonus cooking rock at chest level:

Using the Coleman multifueler here because I got something physically clogged in the fuel line of the MSR dragonfly.   When I tore down the pump for maintenance/troubleshooting there were bits of the pump’s red plastic collected in places.  I don’t think the clog is that because there is a small filter downstream from the pump.

The fuel line is a bit annoying because the line is somehow crimped onto the burner on one end and a brass block on the other.   A breakdown of a similar model suggests there may be barbs to connect replacement hose to (see below).

I have a support ticket in to MSR asking them if they sell the line.  If not I’ll cut it off and roll my own with some fuel line and SS braid.  I’d like a bit longer line anyhow.  I’d really, really like to tear into the line now to see and measure the barbs and start planning a replacement but I’ll leave it intact until I hear back from MSR.




backchannel: buddy heater CO

Before I start — I have no problem with informed folks running a stove as a heater.

from this post:

I got banned [from a FB group] because I said that one could use a propane stove as a heater even though I made the point that a buddy heater actually creates more CO than the stove

It is not clear to me why one’s CO output would differ from the other (all other things being equal).  I have a CO monitor in my van and it has never come off zero with either the Buddy or stove running (both, when making coffee in the morning).

And in low oxygen environments the Buddy will shut off and the stove will not, creating drastically higher CO.  Buddy also has a tip sensor.

I wonder if OP is confusing the glow of the ceramic element with the color of incomplete combustion.

What am I missing here?








pressure cookers for nomads

I can hear you already:  “Fieldmouse, you must be out of your mind!  Pressure cookers are big, heavy things that just take up space.”

Hear me out.

Pressure cookers for cooking

Let’s start with the obvious thing first, cooking.  You have probably heard your grandmother, aunt, or uncle rave about how fast a pressure cookers (PCs) cook food.  They certainly are faster than everything but a microwave but there are nomad-friendly aspects that are often overlooked: Continue reading “pressure cookers for nomads”
