The procedure is as follows :----

Relieving Fuel System Pressure

CAUTION

Be sure that the ignition switch is OFF before relieving the fuel system. Never smoke while working on the fuel system!

1.8L, 3.0L & 3.2L ENGINES

See Figure 1

Fig. Fig. 1: Slowly turn the banjo bolt on the fuel filter to relieve the fuel system pressure

1. Disconnect the negative battery cable.
2. Remove the fuel filler cap.
3. Using a 12mm box-end wrench, loosen the banjo bolt from the top of the fuel filter. Be sure to hold the fuel filter with another wrench.
4. Place a shop towel over the banjo bolt to absorb any fuel that may leak out as the bolt is loosened.
5. Slowly unscrew the banjo bolt one turn.
6. Always replace the washers whenever the bolt is loosened.
7. After the fuel system pressure is relieved, Tighten the service port bolt, install the fuel filler cap, then connect the negative battery cable.

2.2L, 2.3L & 2.5L ENGINES

1. Disconnect the negative battery cable.

How to replace Fuel Pressure Regulator on Acura Car models?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The procedure is as follows :-----

Fuel Pressure Regulator

REMOVAL & INSTALLATION

The fuel pressure regulator keeps a constant fuel pressure to the fuel injectors. When the manifold pressure and fuel pressure vary more than 43 psi (294 kPa) the diaphragm is pushed upward causing the excess fuel to be fed back into the fuel tank through a return line.

CAUTION

Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion. See Figure 1

Fig. Fig. 1: Cross-sectional views of the fuel pressure regulator in both the open and closed positions

1. Properly relieve the fuel system pressure.
2. Disconnect the negative battery cable.
3. Detach the vacuum hose from the fuel pressure regulator.
4. Unfasten the two fuel pressure regulator retaining bolts.
5. Remove the fuel pressure regulator and the O-rings. Discard the O-rings.

To install:

6. Lubricate the new O-rings with a light engine oil.
7. Position a new O-rings onto the fuel pressure regulator.
8. Place the fuel pressure regulator into position and install the retainers.
9. Attach the vacuum line to the fuel pressure regulator.
10. Connect the negative battery cable.
11. Run the engine at idle for 2 minutes, then turn the engine OFF and check for fuel leaks and proper operation.
