Installation Diagram
Valve 1
Valve 2
Fuel Tanks Above Filter
Do not exceed 39’ (11.9 m)
of head feet or 15 PSI.
Fuel Tank
(Pressure Side Installation)
A shut-off valve is
recommended when the
fuel tank is mounted higher
than the filter
Fuel Tank Below Filter
Do not exceed 5’ (1.5 m) of lift
or 4 inches of mercury (inHg)
of inlet piping restrictions
Fuel Tank
(Ideal Vacuum
Side Installation)
Fuel Tank
(Vacuum Side Installation)
Install a check valve
(with light or no restriction)
when tank is lower than filter
to maintain prime.
Pressure Side:
Fuel transfer pump not to
exceed maximum PSI
or flow rate of filter.
NOT ideal - pumps emulsify
water hindering filter
performance.
Fuel transfer pump
(IDEAL vacuum side installation)
Engine
Maintain a service clearance below
filter assembly of at least 2 in. (5.1 cm)
for draining and servicing bowl.
Valve 3
Suction (vacuum) Side:
Primary (first) filter - use 30 micron.
If it is the
only
filter in the system,
use 2 or 10 micron.
Maintain a clearance above the filter assembly
of 5 in. (12.7 cm) (900FH),
and 10 in. (25.4 cm) (1000FH)
for filter removal.
Optional Bypass Installation and Operation
(allows user to service filter without shutting down engine.)
