6.5 Fuel Filter
The fuel filter is installed between the fuel feed
pump and fuel injection pump for 3JH4E and
4JH4E and between the fuel tank and fuel injection
pump (feed pump) for 4JH4-TE and 4JH4-HTE.
The fuel filter removes dirt/ foreign matter from the
fuel pumped from the fuel tank.
The fuel filter element must be changed
periodically. The fuel pumped by the fuel feed
pump goes around the element, is fed through the
pores in the filter and discharged from the center of
the cover. Dirt and foreign matter in the fuel are
deposited in the element.

The fuel strainer must be cleaned
occasionally. If there is water or foreign matter
in the strainer bowl, disassemble the strainer
and wash with clean fuel oil to completely
remove foreign matter. Replace the element
every 250 hours of operation or every year,
whichever comes first.
Replace the filter prior to this if the filter is very
dirty, deformed or damaged.
