SP8-10. FUEL FILTERS
1. Your generator set should have a primary fuel fi lter
installed. We recommend the Northern Lights brand
of fuel fi lter-water separators.
a. Check the primary fuel fi lter daily as
recommended by the fi lter manufacturer.
Empty the collection bowl as necessary.
b. Change the element as often as necessary or
every 200 hours.
c. If the bowl fi lls with water, change the primary
and secondary element immediately.
Figure 9: Primary Fuel Filter
2. Change secondary fuel fi lter every 200 hours.
NOTE: The fuel fi lter on the engine is considered
the “secondary fuel fi lter”.
a. Remove the spin-on fi lter by turning it counter-
clockwise with a fi lter wrench. Fill the new
cartridge with fuel and install it after applying
engine oil to the gasket surface. Screw on the
fi lter until the gasket surface comes into contact
with the sealing surface of the fi lter base. Then,
tighten it two-thirds of a turn by hand. Do not
overtighten.
