Description
The fuel filter / water separator module
provides fine particle filtration, water
separation, water in fuel sensing,
automatic water draining, lifetime
purification of drained water with a
charcoal filter, 12v preheating and
system manual priming in a singular
easy to service module.
NOTE
The engine and fuel module should
be operated in cold climates with
acceptable cold climate fuel blends
which noticeably reduces wax
gelling of the fuel filter cartridge. The
fuel module includes a 12 - volt pre-
heater to support preheat of the fuel
for initial start-up in mild climates.
Failure to operate with acceptable
cold climate fuel may result in insuf-
ficient fuel flow to the fuel injection
system.
