(f) Set the fuel pump lifter assembly on the fuel pump lifter guide as shown in the illustration.

HINT:

Align the stopper key of the fuel pump lifter assembly with the key groove of the fuel pump lifter guide.

(g) Apply engine oil to a new O-ring and install it to the fuel pump assembly.

NOTICE:

Do not damage the O-ring.

(h) Set the fuel pump flange and fuel pump assembly on the cylinder head cover sub-assembly as shown in the illustration.

(i) Temporarily install the fuel pump assembly with the 2 bolts, leaving some allowance for left and right movement.

2. TEMPORARILY INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY

NOTICE:

Do not damage the seals of the union nuts of the No. 1 fuel pipe sub-assembly.

(a) Connect the No. 1 fuel pipe sub-assembly to the fuel delivery pipe and tighten the union nut by hand.

(b) Connect the No. 1 fuel pipe sub-assembly to the fuel pump assembly and tighten the union nut by hand.

(c) Temporarily install the bolt.

3. INSTALL FUEL (ENGINE ROOM SIDE) PUMP ASSEMBLY

(a) Tighten the 2 bolts.

Torque:

28.5 N·m {291 kgf·cm, 21 ft·lbf}

(b) Connect the fuel pump assembly connector.

4. INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY

(a) Using a 17 mm union nut wrench, tighten the union nut on the fuel delivery pipe side of the No. 1 fuel pipe sub-assembly. Torque: Specified tightening torque : 35 N·m {357 kgf·cm, 26 ft·lbf} NOTICE: Do not adjust the torque in the loosening direction. HINT: Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

*a 17 mm Union Nut Wrench *b Torque Wrench Fulcrum Length

(b) 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.

Torque:

Specified tightening torque :

35 N·m {357 kgf·cm, 26 ft·lbf}

NOTICE:

Do not adjust the torque in the loosening direction.

(c) Using an 8 mm socket wrench, tighten the bolt.

Torque:

10 N·m {102 kgf·cm, 7 ft·lbf}

(d) Connect the ignition coil assembly connector.
