  Q: How to service the fuel filter/fuel pressure regulator located at the top of the fuel pump module on the fuel tank on Dodge Ram 3500 Van?

  A:

  You can find the fuel filter/fuel pressure regulator above the fuel pump in the fuel tank, so don't forget to let go of the fuel system pressure before servicing. The first step is to eliminate the fuel tank by taking out the fuel and then removing it. Keep the space around the filter/regulator clean so nothing gets into the pump module. The filter/regulator is pushed into a grommet and needs to be twisted and pulled away, but not more than three inches above the fuel pump module. Cut the old clamp off very gently so you don't damage the fuel tube and then remove and get rid of the old clamp. Slide down the plastic fuel tube and take out the filter/regulator from the fuel pump module. First, clamp the plastic fuel tube using a fresh clamp, then install the filter/regulator onto the fuel tube so that it faces the driver's side of where you are installing it. Use Hose Clamp Pliers number C-4124 to clamp the line and don't use conventional side cutters, as the clamp may be damaged. Fit the filter/regulator into the rubber grommet and place it so the driver's side edge is in front. After that, attach the fuel tank and look for possible fuel leaks.

  Q: How to access and install the fuel pressure regulator on Dodge Ram 3500 Van?

  A:

  Above the fuel cylinders on the left side, the fuel pressure regulator is fastened to the fuel cylinder carrier and reaches two rubber hoses that move engine coolant. When accessing the pressure regulator, set the left and right wheel assemblies and the fuel cylinder carrier assembly to their lowest position, always reading the Warnings and Cautions. Always begin by cleaning the pressure regulator's line fittings, after that cut the fuel line and the pressure relief line. Take the two bolts out holding the regulator on the fuel cylinder bracket and withdraw the regulator from it. To install, fit the pressure regulator onto the fuel cylinder carrier bracket, put thread lock on the bolts and screw and tighten the two bolts to 9 Nm (80 in. lbs). Install the high-pressure fuel line and pressure relief discharge line on the pressure regulator and use a Go No-Go gauge to check their fittings after tightening. Finally, set the fuel cylinders and fuel cylinder carrier on the left-hand side, in line with all the warnings and caution names listed in the manual.
