Fuel Lift Pump
- Cleaning the Strainer
To remove and fit pump, see Engine Service Manual.
Remove and clean fuel inlet strainer 2 if blockage is
suspected ie. low engine power, difficult to start, fuel tank
contamination.
1 Allow the engine to cool. Remove the fuel filler cap to
vent the system and reduce loss of fuel. Disconnect the
fuel inlet pipe to the lift pump.
2 Unscrew the fuel filter A. Remove strainer 2 and O-ring
3.
3 Clean the strainer in clean diesel fluid and dry with low
pressure compressed air. Renew the strainer and O-
ring if damaged.
4 Fit the strainer into the fuel inlet connection. Fit the inlet
connector A and tighten to 20Nm (15 lbf ft). Fit the fuel
inlet pipe carefully to prevent damage to the strainer,
and tighten the union nut.
IMPORTANT: The fuel strainer can be damaged and fuel
flow can be restricted if the fuel pipe is inserted too far
into the inlet connection. This should be checked if a fuel
restriction is suspected.
Make sure the olive on the fuel inlet pipe is in good
condition and forms an effective seal. Renew the olive
or pipe if necessary to prevent air entering the fuel
system.
5 Fit the tank cap and prime the fuel system. Start the
engine and check for fuel leakage.
