FUEL FILTER RECOMMENDATIONS FOR
ETHANOL BLEND FUEL
Because ethanol will act as a solvent and will attract
and hold moisture, Crusader Engines has removed the
Primary Fuel Filter or Fuel Pre-Filter and in its place a
fi tting will be provided for connection to a spin-on type
fuel/water separator.
A spin-on type fuel/water separator fi lter, of 10 micron
fi ltering capability with a minimum rating of 90 gallons
per hour is required between the low pressure fuel pump
and the fuel source. Crusader Engines recommends the
use of Crusader part number RA080033. This is a 3-
piece, RACOR, fuel/water separator. This unit allows for
the easy draining of water and contaminate inspection
between service intervals, without the need to replace
the fi lter element during an inspection.
Crusader Engines recommends that the fuel/water
separator be mounted as low as possible, relative to the
fuel source, away from heat, such as exhaust runs, and
in an easily accessed and serviceable area.
Upon initial installation or service of the fuel/water
separator, the fi lter element should be pre-fi lled with
fresh fuel prior to mounting the element to the head.
Pre-fi lling the fi lter element, with fresh fuel, will reduce
the time required to prime/re-prime the fuel system after
a service interval.
Refer to the diagram below for height, width, depth,
and the minimum under bowl clearance for service
dimensions for the RA080033 fuel/water separator.
