IMPORTANT NOTICE
Any work in the fuel supply system must be carried out by skilled personnel only.
Compliance with all the safety rules and environmental protection rules according
to your local laws is strongly recommended.
• Ensure no voltage is present in the pump circuit by removing the ground cable
connection from the battery.
• Follow the correct circuit polarity to avoid pump damages.
• Always clean carefully the tank and the fuel hoses: dirt is the main failure cause
of recently replaced fuel pumps.
• Never install a new pump without its filter, always replace the old filter; in case of
defect claim for guarantee replacement, the fuel pump must be delivered back
together with its filter.
• In-line pumps must always be installed below the tank level: the fuel has to reach
the pump inlet by simple drop, otherwise the pump becomes overheated.
• In case of in-tank units, remember to remove the air from the fuel supply circuit.
To this purpose, turn on shortly the pump unit until the fuel comes out from the
return hose and, at this moment, shut off the pump and close the fuel circuit by
re-connecting the return hose to the relevant unit cover inlet.
• Check the in-tank unit cover fittings for leakages and ensure that any cover
marking (if present) is corresponding to the relevant position marking when the
cover is fitted back into its location.
