  Q: How to service the fuel rail assembly on Dodge Ram 1500 Van?

  A:

  The fuel system should be deflated before any work is done on the fuel rail assembly. For this, use the Fuel System Pressure Release Procedure. Connectors for the hose are tightened only by fitting the assembly together, everything is pre-connected. When detaching the fuel rail assembly, avoid putting a bend or kink in the connecting hose. Take off the engine cover, pull out the negative battery cable and detach the air cleaner. After performing the fuel pressure release, take out the throttle body from the intake manifold. Air conditioned cars should have an A/C compressor bracket. Take out the three bolts to remove it. Disconnect the fuel injector connectors, marked INJ 1, INJ 2 and so on and the electrical connector from the intake manifold air temperature sensor without taking out the sensor. Take out the clamp on the fuel rail's fuel tube, slacken the rest of the fuel rail bolts and give the fuel injectors on the intake manifold a good clean. With firm pleasing strokes, rock and draw the two fuel rails apart until everything is clear inside the intake manifold, after which you can remove the entire assembly with attached injectors. Take out the clips holding the injectors to the fuel rail. You should apply just a little engine oil to the O-rings on each fuel injector. After that, place them and the clips onto the fuel rail during installation. Help each injector into its opening on the intake manifold, being careful not to tear the O-ring as you do. Make sure the injectors hit their injector shoulder on the rail before bottoming out on the fuel rail. Mount the fuel rail with the correct bolts, put the electrical connection back on the intake air temperature sensor and join the wires to every fuel injector. Set the A/C support bracket in place if you have it and then join the throttle body to the intake manifold. Reassemble the fuel line on the side of the rail, complete connection of the air cleaner, reattach the battery cable, start the car to check for holes and fit the cover.

  Q: How to service the fuel rail assembly on Dodge Ram 1500 Van?

  A:

  Before servicing the fuel rail assembly, always let any fuel system pressure out. Lift off the engine cover, remove the negative battery cable and get rid of the air cleaner. Preform the fuel pressure reset, then take out the throttle body from the air intake manifold. When air conditioning is installed, you must take out the A-shaped support bracket connected between the A/C compressor and intake manifold with these three bolts. Disconnect the wiring connectors at each fuel injector labeled with an ID. Loosen the electrical connector at the intake manifold air temperature sensor for the 3.9L V-6; do not remove the sensor. Take off the fuel tube at the side of the fuel rail and then pull out the remaining bolts that secure the fuel rail. Remove dirt from every fuel injector at the intake manifold and then rock and gently pull the left and right fuel rails until the fuel injectors clear the intake manifold. Get rid of the entire fuel rail and its attached injectors and also remove the clips that hold the injectors on the rail. Put a drop of engine oil onto each O-ring of a fuel injector and then install both the injector and the clip onto the fuel rail. Center the fuel rail/fuel injector assembly over the intake manifold openings so that you can carefully seat each injector in place, not damaging the O-ring. Push the fuel rails down with the injectors fully seated and afterward, screw the fuel rail mounting bolts in place. Restart your connection to the manifold air temperature sensor and extend the wires to all the fuel injectors. Should this apply, fit the A/C support bracket and the throttle body back to the intake manifold. Bring the disconnected fuel tube together at the side of the rail, replace the air cleaner, connect the battery cable, start the engine to ensure there are no leaks and finally, reattach the engine cover.
