How to clean the gauze strainer of the fuel lift pump
1. Loosen the fastener (A2) and remove the cover and joint (A4) from the top of the fuel lift pump (A3) and remove
the gauze strainer (A1).On some turbocharged 6-cylinder engines, it will be necessary to remove the small heat
shield (A4) which is fitted above the pump. Remove the fuel pump (B), then remove the joint and fuel nut, and
then wash them with clean diesel oil.
2. Carefully wash all the sediment from the lift pump body.
3. Clean the gauze strainer, joint and cover.
4. Assemble the lift pump. Use a good joint and ensure that the lift pump body and the cover are fitted together
correctly. Because leakage at this point will let air into the fuel system. On some turbocharged 6-cylinder engines,
fit the heat shield.
5. Eliminate the air from the fuel system through the filter vent point (see page 4.11).
Fuel pre-filter
If a fuel pre-filter is fitted between the fuel tank and the engine, check the filter bowl for water at regular intervals and
drain as necessary.
