Installation Guidelines
These
customer supplied
materials should be on hand
before beginning installation.
• Shop Towels
• Mounting Hardware
• Inlet/Outlet Fittings
• Fuel Hose
• Clean Diesel Fuel
• Clean Motor Oil
• Thread Sealant (no thread tapes)
Positioning The Filter Assembly
Install filter assembly on suction
side of fuel transfer pump for
optimum water separating
efficiency.
See Installation Diagram.
Keep fuel line restrictions to
a minimum. Locate the filter
assembly between horizontal
planes of the bottom of the fuel
tank and inlet of fuel pump, if
possible. If the filter assembly is
installed in an application where
the fuel tank is higher than the
filter, a shut-off valve must be
installed between the tank and
filter assembly INLET. This will
be used when servicing the
replacement filter.
BEFORE Installing The Filter
Assembly
• Obtain good ventilation and
lighting.
• Maintain a safe working
environment.
• Engine must be off for
installation.
• DO NOT smoke or allow open
flames near installation.
Installing The Filter Assembly
• Completely remove any suction
side filters in fuel line between
fuel tank and fuel pump. This is
where the Racor filter will mount.
Leaving these filters in place will
add to fuel system restriction.
Filter heads cast into the engine
or that are non-removable or
hard piped should be serviced
with a new filter and left in place.
• Keep fuel flow restriction
to a minimum. Always use
the maximum size fuel hose
possible. Do not make sharp
bends with flexible hose as kinks
may occur. Avoid use of two 45°
elbow fittings where one 90°
elbow will work.
• When routing hose, avoid
surfaces that move, have sharp
edges, or get hot (such as
exhaust piping).
• Avoid using one-way check
valves that have an opening
pressure higher than 0.5 PSI
(0.03 bar).
Priming Instructions
1. Remove T-handle and lid from
top of filter assembly.
2. Fill filter with clean fuel.
3. Lubricate lid gasket and
T-handle O-ring with clean fuel
or motor oil.
4. Replace lid and T-handle and
tighten snugly by hand
only—do not use tools.
5. If applicable, refer to
equipment operator’s service
manual to complete fuel
priming procedure.
6. Start engine and check for
fuel system leaks. Correct as
necessary with engine off and
pressure relieved from filter
assembly.
Service Instructions
Draining Water
Frequency of water draining is
determined by the contamination
level of the fuel. Inspect or drain
collection bowl of water daily or as
necessary. Collection bowl must
be drained before contaminants
reach the bottom of the turbine
(inside the bowl), or when the
Water Detection Module (optional)
indicates a drain is required.
Pressure Side
Applications
1. Open self-venting drain
on bottom of bowl. Head
pressure will push any water
and contaminants out of drain
while keeping filter primed.
2. Close drain after all water
and contaminants have been
evacuated—DO NOT leave
drain open too long as it will
eventually completely drain
entire filter of water AND fuel,
and possibly drain entire tank.
Suction Side
Applications
1. Close inlet valve (or valve #1)
and open self-venting drain on
bottom of bowl.
2. Close drain after all water
and contaminants have been
evacuated—DO NOT leave
drain open too long as it will
eventually completely drain
entire filter of water AND fuel.
3. Follow
