Lubricate the o-ring seal with clean lubricating oil.
CAUTION
Mechanical overtightening can distort the threads as
well as damage the filter element seal or filter can.
CAUTION
Do not pre-fill the pressure side fuel filter with fuel
unless a clean side block off plug is used. The system
must be primed after the fuel filter is installed. Pre-
filling the pressure side fuel filter can result in debris
entering the fuel system and damaging fuel system
components.
NOTE: If available, pre-fill new filters, both pressure side
and suction side, with clean fuel prior to assembly using
the clean side block off plug packed with the filter. Do not
pour fuel directly in the center of the filter, since this will
allow unfiltered fuel to enter the system and can cause
damage to fuel system components.
Use the following procedure for the correct fuel filter part
number. Refer to Procedure 018-024 in Section V.
Install the filter on the filter head. Tighten the filter until the
gasket contacts the filter head surface.
Tighten the fuel filter an additional ¾ turn after contact or
follow filter manufacturer instructions.
