Removal and installation of the pressure regulator

Withdrawal

Disconnect the ground wire from the battery clamp.

Remove the air filter.

Install a container to collect the escaping fuel from the CFJ.

Loosen the high pressure flexible hose connection and let the fuel pressure drop. Disconnect the high pressure hose. as well as a fuel overflow line.

Disconnect the gas pedal linkage.

Drain the liquid from the cooling system.

Disconnect the electrical wire connectors from the CFJ control unit.

Remove the plug from the pressure regulator cover and unscrew the hex head bolt.

Remove the pressure regulator cap.

Remove the remaining parts of the regulator (pic. 2.127).

Installation

Assemble the regulator parts as shown in fig. 2.127. Tighten the cover bolts evenly.

Insert the valve ball and position it in such a way that it is securely seated in the washer (plate) springs.

Screw in the hex socket head bolt to the stop and unscrew it from this position by approximately three turns.

Attach the CFJs to the intake manifold.

Connect a pressure gauge to check the fuel pressure (pic. 2.128).



Connect fuel lines.


Establish draft of a pedal of gas.

Connect the connections and connectors of the electrical equipment.

Connect the pipes of the cooling system and fill it with coolant.

Connect the vacuum tube.

Close the fuel pump switch so that the pump runs without interruption. The pressure of the fuel supplied by the pump must be 1.0±0.05 bar.

If fuel pressure adjustment is required, turn the hex socket head bolt with a 4 mm hex wrench. Turning the bolt should cause a pressure drop of up to 0.5 bar. Turn the bolt in the opposite direction until the fuel pressure rises to 1.0 bar (pic. 2.129).



Install a new plug in the seat of the regulator cover.

Start the engine and check the fuel lines for leaks.

Install the air filter.
