And how much would in cost in fuel filters? Maybe in an old Detroit
Diesel. But not in any new diesel with a high pressure pump.


I have horrible visions of all those nearly invisible metal filings, carbon
particles and other microscopic contaminants grinding away between the fuel
pump pistons and those finely precision holes to .0001" tolerances they
pump so carefully into. Combine the solid contaminants too small to filter
with all the acidic blowby chemistry, the reason we change the oil so often
in a diesel engine, and I'd think it wouldn't take long to simply eat away
at the inside of the amazingly-expensive injection pump, primary pump, and
the tiny nozzles' guts in the cylinders.

Yecch.....all for a few bucks saved on a tank? I suppose if we're going to
do this, we could also slowly dump the electrolyte from those old batteries
in the fuel tank, too, to eat away at it all quicker!
