We run 100% biodiesel on our tug, Ernest Hemingway, and use the Racor
twin turbine filter system with pressure gauge (75500FGX FUEL
FILTER/WATER SEPARATOR) with a heavy duty electric fuel pump
. This system serves multiple purposes from standard fuel filtering, fuel polishing, and engine
priming to using fuel to ballast the tug in heavy winds among the various fuel tanks
. We can also use the system to fuel our tender
and syphon fuel from Jerry cans. No electronics
to fail. Simply carry extra filters and a spare pump with quick connects. Simple and robust.
