NOTICE
Do not fill fuel filters with fuel before installing
them. The fuel will not be filtered and could be
contaminated. Contaminated fuel will cause ac-
celerated wear to fuel system parts. The fuel sys-
tem should be primed prior to starting the engine.
Water in the fuel can cause the engine to run rough.
Water in the fuel may cause an electronic unit injector
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 to help extend the life of the secondary fuel
filter. The element should be changed regularly. If a
vacuum gauge is installed, the primary filter/water
separator should be changed at 50 to 70 kPa
(15 to 20 inches Hg).
