Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge.
