Installation

1UR-FSE FUEL: FUEL PUMP (for High Pressure): INSTALLATION

1. INSTALL FUEL PUMP ASSEMBLY (for Bank 1)

(a) Turn the camshaft until the flat of the cam is facing the cylinder head cover's fuel pump attachment hole, as shown in the illustration.

HINT
By not using the camshaft lobe to push up the pump lifter surface, it is easier to install the fuel pump and No. 3 fuel pipe later.

(b) Pour 30 cm3 (1.8 cu. in.) of engine oil through the cylinder head cover's fuel pump attachment hole into the cylinder head oil collector.

(c) Apply a coat of engine oil to the pump activation cam and pump lifter.

(d) Install a new fuel pump insulator to the cylinder head cover. Then pass the 2 stud bolts through the holes of the fuel pump and set them on the insulator.

NOTICE:
Install the insulator so that the open sides of the metal eyelets are facing outward, as shown in the illustration.

(e) Temporarily install the fuel pump with the 2 nuts.

(f) Connect the fuel hose.

2. INSTALL NO. 3 FUEL PIPE SUB-ASSEMBLY

(a) Install a new O-ring, new backup rings (No. 1 and No. 2) and new E-ring to the fuel injector as shown in the illustration.

NOTICE:
* Check that there is no foreign matter or damaged areas in the injector's O-ring groove.
* Check that the No. 1 and No. 2 backup rings are installed in the correct direction.
* Make sure that the backup rings and O-ring are installed in the correct order.
* Check that the alignment openings of the backup rings are not overlapped or stretched as shown in the illustration.
* After installing the O-ring, check that it is not contaminated with foreign matter and is not damaged.

(b) Temporarily install the No. 3 fuel pipe to the delivery pipe with the 2 bolts.

NOTICE:
Be careful not to damage the sealing surface of the fuel pipe when temporarily installing the fuel pipe.

(d) Tighten the 2 bolts in several passes.

Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)

(e) Tighten the 2 nuts in several passes.

Torque : 25 Nm (255 kgf-cm, 18 ft-lbf)

(f) Using a 19 mm union nut wrench, tighten the union nut.

without union nut wrench - Torque : 30 Nm (306 kgf-cm, 22 ft-lbf)

with union nut wrench - Torque : 27 Nm (275 kgf-cm, 20 ft-lbf)

NOTICE:
There must be absolutely no free play in the union on the fuel pump side. If the union on the fuel pump side has free play, replace the fuel pump.

HINT
* Use a torque wrench with a fulcrum length of 30 cm (11.8 in.).
* Make sure use union nut wrench and torque wrench are connected in a straight line.

(g) Connect the fuel pump connector.

3. INSTALL COVER SUB-ASSEMBLY (for Bank 1)

(a) Attach the 5 claws and install the engine cover LH and RH to the fuel pump.

4. INSTALL FUEL PUMP ASSEMBLY (for Bank 2)

HINT
The installation procedures are the same as the bank 1 side.

5. INSTALL NO. 2 FUEL PIPE SUB-ASSEMBLY

HINT
The installation procedures are the same as the No. 3 fuel pipe sub-assembly.

6. INSTALL COVER SUB-ASSEMBLY (for Bank 2)

HINT
The installation procedures are the same as the bank 1 side.

7. INSTALL FUEL PRESSURE PULSATION DAMPER ASSEMBLY

(a) Install the fuel pressure pulsation damper Installation.

8. ADD ENGINE COOLANT Service and Repair

9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

10. PERFORM INITIALIZATION

(a) Perform initialization Repair Instruction - Initialization.

NOTICE:
Certain systems need to be initialized after disconnecting and reconnecting the cable to the negative (-) battery terminal.

11. ADD ENGINE COOLANT Service and Repair

12. INSPECT FOR COOLANT LEAK Component Tests and General Diagnostics

13. INSPECT FOR FUEL LEAK Fuel System
