The VANTAGE 500 Cummins is equipped with a Fuel
Filter/Water Separator located after the lift pump and
before fuel injectors.The procedure for changing the fil-
ter is as follows. See Figure D4.2
1. Close the fuel shutoff valve.
2. Clean the area around the fuel filter head. Remove
the filter. Clean the gasket surface of the filter head
and replace the o-ring.
3. Fill the clean filter with clean fuel, and lubricate the o-
ring seal with clean lubricating oil.
4. Install the filter as specified by the filter manufactur-
er.
5. Open the fuel valve and check for leaks.
Mechanical overtightening will distort the threads,
filter element seal or filter can.
There is also a Fuel Strainer mounted just above the
shut-off valve. See Figure D4.2. It is designed to pre-
vent larger particle from entering the fuel system. There
is no maintenance possible. If fuel flow seems restrict-
ed, replace the fuel strainer.
