Removal Procedure
The noise cancelling foam component MUST be replaced if it has been exposed to engine fluids. Failure to replace the noise cancelling foam component that has been exposed to engine fluids may result in an engine fire resulting in catastrophic engine damage, and possible injury or death.
Fuel/gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
Wear safety glasses in order to avoid eye damage.
- Relieve the fuel system pressure. Fuel Pressure Relief
- Disconnect the battery negative cable. Battery Negative Cable Disconnection and Connection
- Intake Manifold - Reposition - Intake Manifold Replacement (Except Hybrid)Intake Manifold Replacement (Hybrid)
- Fuel Injection Fuel Rail Noise Shield - Reposition - Fuel Injection Fuel Rail Noise Shield Replacement
Disconnect the electrical connector (1).
- Do NOT apply force to the plastic housing of the fuel injection fuel rail fuel pressure sensor. ONLY apply force to the attached hexagon.
- Some fuel may leak from the fuel injection fuel rail orifice after the sensor is removed. Dry the area around the orifice using a lint free cloth.
- After removal, the area around the fuel injection fuel rail sealing surface should be inspected. The surface should be free of fuel, dirt, debris, and burrs.
- Remove the fuel injection fuel rail fuel pressure sensor (2).
It is NOT necessary to completely remove the intake manifold to gain access to the fuel injection fuel rail fuel pressure sensor.
