  Q: How to service and repair the fuel pressure regulator on Dodge Ram 2500 Van?

  A:

  Make sure you release the fuel system pressure before you try to fix or repair the fuel pressure regulator. You can find the fuel filter/fuel pressure regulator at the top of the fuel pump module on the fuel tank and you don't need to remove the fuel pump module to reach it. Remove the fuel tank from the vehicle by starting with the removal of its fuel. Thoroughly clean the region next to the filter/regulator to keep dirt out of the pump. Remove the fuel filter/regulator from its rubber grommet by twisting it and pulling carefully straight up, making sure you don't pull it more than three inches from the pump module to protect the coiled fuel line. Be careful not to damage the fuel tube as you cut the old clamp and next remove the plastic tube from the filter/regulator. To install the system, first secure a new clamp onto the plastic fuel tube, add the filter/regulator to the fuel line and rotate it so the other end faces the driver's side. Slide the special Hose Clamp Pliers number C-4124 or an equivalent alternative into the line clamp to close it tightly; do not try to cut it with regular side cutters. Simply seating the filter/regulator into the rubber groove, ensuring it faces the driver's seat. Afterwards, fit the fuel tank securely and check if any fuel might be leaking.

  Q: How to access and install the fuel pressure regulator on Dodge Ram 2500 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.
