Fuel Feed Intermediate Pipe Replacement

Fuel Feed Intermediate Pipe Replacement (LLT)

Removal Procedure

1. Remove the Intake manifold cover. Refer to Intake Manifold Cover Replacement (Intake Manifold Cover Replacement).
2. Remove the pressure pump shield. Refer to Fuel Pipe Shield Replacement (LLT) (Fuel Pipe Shield Replacement)Fuel Pipe Shield Replacement (LF1) (Fuel Pipe Shield Replacement).
3. Relieve fuel system pressure. Refer to Fuel Pressure Relief (Service and Repair).




4. Remove the foam insulator from the pipes.
5. Loosen the high pressure pipe fitting to the high pressure fuel pump (1).
6. Loosen the high pressure pipe fitting to the left fuel rail (3).
7. Remove the high pressure fuel pipe (2) from the vehicle. Discard the pipe.

Installation Procedure

1. Lubricate the pipes with silicon free engine oil. Refer to Adhesives, Fluids, Lubricants, and Sealers ([1][2]Fuel Delivery and Air Induction).




2. Position the NEW high pressure fuel pipe (2) to the high pressure fuel pump fitting (1) and left fuel rail (3). hand tighten the fitting.

Caution: Refer to Fastener Caution (Fastener Caution).

3. Tighten the high pressure fuel pipe fitting.

1. Tighten the fitting a first pass to 15 Nm (11 lb ft).
2. Tighten the fitting a final pass to 30 Nm (22 lb ft).

Note: If a fuel leak accrues at the high pressure fuel pump or the fuel rail, that component will need to be replaced.

4. Inspect for leaks using the following procedure:

1. Turn ON the ignition, with the engine OFF for 2 seconds.
2. Turn OFF the ignition, for 10 seconds.
3. Turn ON the ignition, with the engine OFF.
4. Inspect for fuel leaks.

5. Install the low side fuel pressure service port cap.
6. Install the fuel tank cap.
7. Install the high pressure pump shield. Refer to Fuel Pipe Shield Replacement (LLT) (Fuel Pipe Shield Replacement)Fuel Pipe Shield Replacement (LF1) (Fuel Pipe Shield Replacement).
8. Install the Intake manifold cover. Refer to Intake Manifold Cover Replacement (Intake Manifold Cover Replacement).
