Troubleshooting
Replace filter every 10,000 miles,
500 hours, every other oil change,
annually, or at first indication of
power loss, whichever occurs first.
For Construction and Agricultural
use, change filter every 300 hours.
Do not over tighten self-tapping
capscrews to avoid stripping out
body threads. After disassembly,
start threads by hand prior to using
tools. Tighten to 55-65 in. lbs.
The hollow aluminum checkball
floats up against the seal when
fuel is stopped, preventing
fuel bleed-back. If unit looses
prime, inspect upstream hose
connections first, disassemble
unit to inspect seal and ball. (It is
normal to hear a "rattling" sound
at any time).
Air bubbles or fuel leakage
appearing from drain may indicate
drain is not closed completely
or seal has been clogged
with contaminants. Tighten or
disassemble and inspect. Tighten to
30-35 in. lbs.
If filter is changed or assembly
drained for any reason, reprime
assembly. Fill to just above top of
filter before replacing lid. It is normal
for the fuel level to drop during use.
This is especially apparent at filter
element change-out.
Hand tighten only! Do not use tools
for leverage. Tighten 70 to 90 in. lbs.
SAE O-ring ports should have a
smooth angled seat for sealing.
Do not scratch this surface. Check
O-ring for damage.
Damaged, worn, or dirty seals will allow air ingestion.
Inspect and replace all seals as needed. Clean the sealing
surfaces of dirt or debris every time the filter is replaced.
If carriage bolt is loose, do not
overtighten it as this may distort the
bracket position.
Heater feed-thru O-ring must not
be damaged or swollen. Tighten to
15-20 in. lbs.
Air bubbles appearing from turbine
are an indication of an upstream leak
between Racor inlet and fuel tank
pick-up tube.
A plug is installed if the water sensor
option is not selected. Tighten to
15-20 in. lbs.
The water sensor, if equipped, is
used in conjunction with a water
detection amplifier and should
activate when water contacts the
tips. Air bubbles or fuel leakage
appearing from sensor may indicate
it is loose or O-ring is damaged.
Tighten to 15-20 in. lbs.
Filter Safety Valve
Drain water (if present) before it
gets to this level. At some time, the
contaminant collection bowl may
become dirty on the inside. Remove
the four bowl ring capscrews and
drop the bowl. Clean the inside
with hot soapy water, dry off and
re-install. Ensure bowl gasket is
cleaned, and lubricate with silicone
grease prior to reuse.
If self-venting drain will not
work when opened, it may be
clogged. Cycle the drain (open-
close) or attach a hose and
briefly apply air (<2-3 PSI) to
dislodge contaminants.
Replace T-handle o-ring and lid
gasket with each filter element
replacement.
