How to Install a 1995 Neon Fuel Pressure Regulator

The Neon is a compact car that Chrysler manufactured under its Dodge brand from 1995 to 2005. The 1995 model had a 4-cylinder, 2.0-liter engine with fuel injection, which requires a highly pressurized fuel system. This requires a fuel pressure regulator to maintain the pressure in the fuel system within a specific range. The fuel pressure regulator in a 1995 Dodge Neon is part of the fuel pump module, which you must remove to install the fuel pressure regulator.

Instructions

    1

    Remove the negative cable from the battery. Open the fuel filler cap and remove the cap for the fuel pressure port on the fuel rail. Place one end of hose C-4799-2 in a gasoline container, and attach the other end of the hose to the fuel pressure port. Allow the fuel to drain into the gasoline container. Disconnect the hose from the fuel pressure port and replace the cap on the port.

    2

    Raise the Neon with a jack and support it on jack stands. Remove the cap from the drain tube at the rear of the fuel tank. Connect one end of a siphon hose to the drain tube and place the other end into a gasoline container. Drain the fuel tank into the gasoline container. Replace the cap on the drain tube.

    3

    Press the quick-connect fittings on the fuel lines to the fuel pump module and detach the fuel lines. Tap the locking ring for the fuel pump module with a hammer and brass punch to turn the locking ring counterclockwise. Remove the locking ring and pull the fuel pump module from the fuel tank. Discard the O-rings for the fuel pump module.

    4

    Pull apart the tabs on the retainer for the pressure regulator. Pry the fuel pressure regulator from its housing with a small pry tool. Lubricate the new O-rings with engine oil and place them onto the fuel pump module. Push the new fuel pressure regulator into position on the pump module. Push the tabs on the retainer for the fuel pressure regulator over the corresponding tabs on the fuel pump module.

    5

    Install the fuel pump module into the fuel tank and place the locking ring into position on the fuel pump module. Turn the locking ring clockwise until it locks into place. Connect to the fuel lines to the fuel pump module.

    6

    Lower the vehicle and fill the tank with fuel. Fasten the filler cap for the fuel tank and connect the cable to the negative battery terminal with a socket wrench.
