Fuel system A fuel pump sucks fuel from the fuel tank through the fuel filter to the fuel injection system or to the carburetor. The fuel pump and fuel injection system are fused, see Electrical System. IMPORTANT! All work on the engine fuel injection system must be carried out at an authorized workshop. WARNING! Be extremely careful when replacing fuel filters or other service work on the fuel system. Gasoline is highly inflammable and can be extremely explosive in certain circumstances. Before starting work: switch off the ignition and allow the engine to cool completely. There must be no smoking, naked flames or sparks in the immediate vicinity. Place a rag under fuel connectors and filters when removing. Remove the rag and any fuel spillage immediately and dispose of it in a safe place. When work has finished: check carefully that there are no leaks. Check both before and after starting the engine. Run the engine compartment fan for at least 4 minutes before starting the engine. To prevent fire and explosion, Volvo Penta fuel system components meet requirements for fuel and fuel vapour containment. Do not substitute automotive or other non-approved parts.

Fuel pumps WARNING! Frequently check fuel pumps for signs of fuel leakage. Should this occur, have it serviced immediately by your Volvo Penta dealer.
A
All carburettor models except the 3.0GL have a single electric fuel pump installed at the front of the engine on the starboard side. The pump wiring is protected by a 6 A circuit breaker (A). The model 3.0GL has a mechanical fuel pump. EFI engines have two electric fuel pumps; a low pressure pump to bring fuel from the boat tank to the engine, and a high pressure pump to supply the fuel injectors both pumps are protected by a single 20 amp circuit breaker (A). All the fuel pumps operate only when the engine is running. If a pump does not operate and/or the engine will not start, check and reset the circuit breaker. See your Volvo Penta dealer if further service is required. IMPORTANT! Do not run engine out of fuel or run the electric fuel pumps dry more than 20 seconds. Running the electric fuel pumps dry will damage the fuel pumps.
