PROCEDURE
TEMPORARILY INSTALL FUEL PUMP ASSEMBLY
| *1 | Fuel Pump Assembly |
| *2 | Fuel Pump Lifter Assembly |
| *3 | Camshaft |
| *a | Correct |
| *b | Incorrect |
| *c | Oil Collection Area |
Turn the crankshaft pulley until the flat of the camshaft faces the fuel pump lifter assembly.
Tech Tips
This prevents the camshaft nose from pushing up the fuel pump lifter assembly when installing the fuel pump assembly.
Fill the fuel pump lifter housing oil collection areas with 30 cc (1.8 cu. in.) of engine oil from the fuel pump assembly hole of the cylinder head cover sub-assembly.
| *1 | Cylinder Head Cover Sub-assembly |
| *2 | Fuel Pump Spacer Gasket |
| *3 | Fuel Pump Lifter Housing |
| *a | Pump Drive Cam (Engine Oil Application Area) |
| *b | Fuel Pump Lifter Assembly (Engine Oil Application Area) |
Apply engine oil to the pump drive cam and fuel pump lifter assembly.
Install a new fuel pump spacer gasket to the cylinder head cover sub-assembly.
| *a | Fuel Pump Lifter Assembly (Engine Oil Application Area) |
| *b | Fuel Pump Lifter Housing (Engine Oil Application Area) |
| *c | Stopper Key |
| *d | Key Groove |
Apply engine oil to the inside of the fuel pump lifter housing and the outside of the fuel pump lifter assembly.
Set the fuel pump lifter assembly on the fuel pump lifter housing as shown in the illustration.
Tech Tips
Align the stopper key of the fuel pump lifter assembly with the key groove of the fuel pump lifter housing.
Apply engine oil to a new O-ring and install it to the fuel pump assembly.
Note
Do not damage the O-ring.
| *1 | Fuel Pump Assembly |
| *2 | Fuel Pump Lifter Guide |
Set the fuel pump lifter guide and fuel pump assembly on the cylinder head cover sub-assembly as shown in the illustration.
Temporarily install the fuel pump assembly with the 2 bolts, leaving some allowance for left and right movement.
TEMPORARILY INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY
Note
Do not damage the seals of the union nuts of the No. 1 fuel pipe sub-assembly.
Connect the No. 1 fuel pipe sub-assembly to the fuel delivery pipe RH and tighten the union nut by hand.
Connect the No. 1 fuel pipe sub-assembly to the fuel pump assembly and tighten the union nut by hand.
INSTALL FUEL PUMP ASSEMBLY
Tighten the 2 bolts.
Connect the fuel pump assembly connector.
INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY
| *a | 17 mm Union Nut Wrench |
| *b | Torque Wrench Fulcrum Length |
Using a 17 mm union nut wrench, tighten the union nut on the fuel pump assembly side of the No. 1 fuel pipe sub-assembly.
Note
Do not adjust the torque in the loosening direction.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)
Using a 17 mm union nut wrench, tighten the union nut on the fuel delivery pipe RH side of the No. 1 fuel pipe sub-assembly.
Note
Do not adjust the torque in the loosening direction.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)
INSTALL FUEL HOSE BRACKET
Install the fuel hose bracket to the cylinder head cover sub-assembly with the bolt.
CONNECT NO. 2 FUEL TUBE SUB-ASSEMBLY
Engage the clamp and connect the No. 2 fuel tube sub-assembly to the fuel pump assembly.
INSTALL FUEL PUMP PROTECTOR
Install the fuel pump protector to the cylinder head sub-assembly with the 2 bolts.
Engage the clamp to connect the fuel tube sub-assembly to the fuel pump protector.
INSTALL NO. 2 ENGINE UNDER COVER
INSTALL INTAKE MANIFOLD
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
INSPECT FOR FUEL LEAK
PERFORM INITIALIZATION
Perform "Inspection After Repair" after replacing the fuel pump assembly.
