- Replace
SMCS Code: 1260-510-FQ; 1263-510-FQ
Water in the fuel can cause the engine to run rough.
Water in the fuel may cause fuel system components
to fail. If the fuel has been contaminated with water,
the element should be changed before the regularly
scheduled interval.
The primary filter/water separator also provides
filtration in order to help extend the life of the
secondary fuel filter. The element should be
changed regularly. The primary filter/water separator
should be changed when the vacuum gauge (if
equipped) registers 50 to 70 kPa (15 to 20 In Hg).
Replace the Element
Fuel leaked or spilled onto hot surfaces or elec-
trical components can cause a fire. To help pre-
vent possible injury, turn the start switch off when
changing fuel filters or water separator elements.
Clean up fuel spills immediately.
