4.4 REMOVAL AND INSTALLATION, FUEL FINE FILTER

When removing the fuel fine filter, a

quantity of fuel will escape. Collect

the fuel and avoid the risk of fire.

Removing the fuel fine filter
1.

Place a container beneath the fuel fine filter

Do not fill the fine filter with fuel until it has

been fitted. The fine filter is filled with fuel by

the primer pump after it has been fitted. This

for the filter attachment is securely attached.

2.

Lightly lubricate the filter sealing ring with

clean engine oil.

3.

Fit the filter element onto the housing.

Tighten the filter element until the sealing

ring abuts. Tighten the filter element a further

∂ to • turn by hand.

4.

Bleed the fuel system. See "Inspection and

adjustment".

5.

Start the engine and check the fuel system

for leaks. If necessary, retighten the filter by

hand.
