4G9 ENGINE (E - W) - Injector and Fuel Pump Assembly (GDI) 11A-6c-5

Cut surface

Backup ring

(2)Fit the backup rings and the O-ring on both ends of the fuel return pipe. Note that the larger backup ring must be installed with the inside cut surface in the direction shown in the illustration.

(3)Lubricate the O-rings on both ends of the pipe with spindle oil or gasoline.

(4)Insert the fuel return pipe ends straight in the respective mounting holes of the pressure regulator and the delivery pipe. Be sure to insert the pipe fully to the stop using care not to twist it.

(5)Tighten the bolts at both ends of the pipe to the specified torque.

"FA FUEL PUMP / FUEL FEED PIPE INSTALLATION

(1)Insert the fuel pump into the mounting hole in the pump camshaft case <for CARISMA> or in the cylinder head <for PAJERO io>, and secure it temporarily with 4 bolts (tighten somewhat with a larger torque than fingertight).

(2)Fit the backup rings and the O-ring on both ends of the feed pipe. Note that the larger backup ring must be installed with the inside cut surface in the direction shown in the illustration.

(3)Lubricate the O-rings on both ends of the pipe with spindle oil or gasoline.

(4)Insert the fuel feed pipe ends straight in the respective mounting holes of the fuel and the delivery pipe. Be sure to insert the pipe fully to the stop using care not to twist it.

(5)Tighten the bolts at ends of the pipe to the specified torque.

(6)Tighten the mounting bolts of the fuel pressure regulator to the specified torque.

(7)Using a torque wrench having the minimum scale of 0.5 Nm, tighten the fuel pump mounting bolts in the following order.

1)Tighten the bolts to 5 Nm in the order given in the illustration.

2)Tighten the bolts to 17 Nm in the order given in the illustration. The torque variation among 4 bolts must be within 2 Nm.

Caution

Strictly observe the specified tightening torque. Deviation from the specification can cause problems such as leakage or the like.
