[Philmont]: Stove Fuel and Coffee Filters

Coffee filter tretise below
 
<<I will add, though, that *both* my stoves that couldn't burn the contaminated fuel in August, 2001 were multi-fuel: One was a Coleman Exponent Feather 442 dual-fuel and one was an MSR Dragonfly multi-fuel. I never did identify the contaminant.

Gary, not tryint to be condescending, but just an educated by many years guess. I'd bet my bottom dollar that the contaminant was fuel and the bulk of the liquid was water. Water is the biggest problem in hydrocarbon fueled anything.
 
Coffee filters.
 
I've never needed to try them to filter fuel, but being a chemical plant laboratory employee who uses many kinds of selective filters, I'd rather think coffee filters would be very low on the choice list to filter out water from fuel.
 
Why? Well, for starters coffee filters are designed for the water to run through the filter. Fuel filters are designed for the exact opposite reason.
 
When using coffee filters as a pre filter for a water filter you want the water to pass through the filter and the suspended matter, clay, sticks, twigs, cow patties, etc to be stopped by the filter.
 
When filtering fuel, you want the fuel to pass through and the clay, sticks, cow patties, etc PLUS the water to be stopped by the filter.
 
One filter cannot do both these things. Think about what a coffee filter is designed to do.
 
There is an old Cajun proverb that says "use the right tool for the job". Of course, a Cajun knows that with bailing wire and a pirogue pole, anything can be fixed.
