Basics

This is a category of Multi-Fuel Liquid Fuel Pressure Stoves that utilize a Liquid Fuel Bottle and Pump / Regulator Assembly SEPARATE from the Burner assembly itself
- This has some advantages in terms of safety, compactness, and modularity
- Outside of the Chinese White Label Multi-Fuel Stoves and Wick based designs, it is the main “state of the art” for these stoves
Some of these can also be run off of Gas Canister Fuel ( Butane , Iso-Butane , Propane or blends of these
While some do not take this approach, ideally you want different nozzles for the different fuels (to change Air-Fuel Ratio and to a lesser extent Fuel Atomization
- Although the “Vapor Generator” and Flame Spreader / Burner Silencer largely negate the need for this
A “Shaker Needle” for cleaning Coke Formation in the vapor generator / nozzle is also a preferred feature over solely manual needle poking / mesh removal + blowtorching etc

History

MSR Pioneered the Concept
- https://cascadedesigns.com/blogs/msr-gear-guides/liquid-fuel-stoves-history
- Granted Biased Page
Seems like most of the other versions were 70’s-2000’s iterations on the concept
- Not MUCH development since, although POTENTIALLY in the “cloners, turned modern proper companies” such as “Campingmoon” etc

”Whisperlight Universal” is their only real remaining model
- This is basically the “Whisperlight International” but with an adapter for use as an Inverted Canister Stove (aka Liquid Feed Canister Stove
The “Dragonfly” and “XGK” are their older models
- The XGK in particular had some use with Diesel/Kerosene/JP-5 etc with military customers and thus had dedicated nozzles for that (although coke formation is increased with heavier/“dirtier” fuels

Primus Multifuel
Primus Omnifuel / Omnifuel II
Primus OmniLight TI
- A Titanium based “ Ultralight “ version of the Omnifuel (which may be the dame as the Omnifuel II, bit uncertain)
