1056F60 SINGLE FUEL MANIFOLD PIPE, COMPLETE WITH INJECTORS - R.R. - Alfa - 156 - eLearn

3237737 - 1056F60 SINGLE FUEL MANIFOLD PIPE, complete with injectors - R.R.

) Position the vehicle on the ramp.DRAIN THE FUEL HIGH-PRESSURE SYSTEM AS DESCRIBED BELOW. Start up the engine.Maintain idle for 2 minutes.Remove the fuel pump relay.Wait for the engine to stall.Try to start the engine: if the engine starts within 10 seconds, wait for it to stall, then try to start it again; if the engine does not start withiin 10 seconds, continue cranking for a further 5 seconds. Wait until the engine cools down. Proceed with removal - 7055B54 under-engine guard - r r . Proceed with removal - 1076B18 rigid section of exhaust pipe between catalytic converter and silencer - r + r . Proceed with removal - 5530B10 battery - r+r . Proceed with removal - 1072D10 modular inlet manifold - r+r . 1. Disconnect the rapid attachment for the fuel bypass pipe, fuel manifold side.2. Undo the connectors (2a), (2b) and remove the high-pressure pipe from the pump to the fuel manifold (2c).

During refitting, use a new high-pressure pipe between pump and fuel manifold.

1. Undo the bolts (1a) and remove the fuel manifold (1b) complete with fuel pressure regulator (1c) and connectors (1d) for the fuel injectors.

Refitting ( Removing

) 1. Refit the fuel manifold (1a) complete with fuel pressure regulator (1b) and injector connectors (1c), then tighten the relevant bolts (1d) to the specified torque.

	Fastening	Component	Ø	Value(daNm)
1d	Bolt	FUEL MANIFOLD	M9	(Intake manifold side) 3.9 ÷ 4.7

1. Refit in its seating a new high-pressure pipe from the pump to the fuel manifold (1a) and tighten the connectors (1b) and (1c) to the specified torque.

To ensure that the pipe is fluid-tight, first tighten the connector on the pressure pump side and then the connector on the fuel manifold pipe side.

	Fastening	Component	Ø	Value(daNm)

	Fastening	Component	Ø	Value(daNm)
1c	Connector	FUEL HIGH PRESSURE PIPE	M12	(Fuel manifold pipe side) 2.0 ÷ 2.4

2. Connect the rapid attachment for the fuel bypass pipe, fuel manifold side.
