5. Eliminate the air from the fuel system through the filter vent point (see 

section 5.8

).

5.5 ChECkING ThE fuEl pRE-fIlTER

Some engines are fitted with a pre-filter of the same main type as the fuel filter 

element (see 5.6 below). This will normally be fitted between the fuel tank and 

the engine and is connected to the main filter but before the fuel lift pump. Both 

elements must be removed at the same time.

Check the fuel bowl for water at regular intervals and drain as necessary.

5.6 RENEWING ThE fuEl fIlTER ElEMENT

There are three fuel filter element types in use (see 

Figure 5.6

).

1.  

Separate Type

The filter element is held between the filter head and the bottom cover.

2.  

Canister Type

The filter element has an internal thread at the top and is fastened to a threaded 

adaptor in the filter head.

3.  

Quick Release Canister Type

This has been introduced on certain engines.

2. Carefully wash all sediment from the 

lift pump body.

3. Clean the gauze strainer, joint and 

cover.

4. Assemble the lift pump. 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.  If  fitted,  refit  the 

heat shield.

5.Eliminate the air from the fuel system 

through  the  filter  vent  point  (see 

section 5.8).

5.5 CHECKING THE FUEL 
PRE-FILTER

Some  engines  are  fitted  with  a  pre-

filter of the same main type as the fuel 

filter element (see 5.6 below). This will 

normally be fitted between the fuel tank 

and the engine and is connected to the 

main filter but before the fuel lift pump. 

Both elements must be removed at the 

same time.

Check the fuel bowl for water at regular 

intervals and drain as necessary.

5.6 RENEWING THE FUEL 

FILTER ELEMENT

There are three fuel filter element types 

in use (see 

Figure 5.6

).

1. 

Separate Type.

 The filter element is 

held between the filter head and the 

bottom cover.

2. 

Canister  Type.

 The  filter  element 

has an internal thread at the top and 

is fastened to a threaded adaptor in 

the filter head.

3. 

Quick  Release  Canister  Type. 

This has been introduced on certain 

engines.

 CAUTION

It  Is  Important  that  only  genuine 

Lister  Petter  fuel  filter  elements 

are  used.  The  wrong  element  can 

damage the fuel injection pump.

5.6.1 Renewing a Separate Type Fuel 

Filter Element

Refer to 

Figure 5.6.1

.

The  filter  can  have  one  or  two 

elements.

When  twin  elements  are  fitted  both 

the elements must be renewed at the 

same time.

5.6.1 Renewing a separate type element

  A. Separate type element 

    B. Canister type element     C. Quick release element

5.6 Fuel filter element types

   A. Separate type element      B. Canister type element  

C. Quick release element

5.6 Fuel filter element types

 

CAuTION

It Is Important that only genuine Lister Petter Power Systems fuel filter elements 

are used. The wrong element can damage the fuel injection pump.

5.6.1 Renewing a Separate Type fuel filter Element

Refer to 

Figure 5.6.1.

The filter can have one or two elements.

When twin elements are fitted both the elements must be renewed at the same 

time.
