How do you change a fuel filter


All WJ models have two fuel filters, a strainer filter at the bottom of the fuel pump module inside the fuel tank and one exterior filter within the fuel pressure regulator. Both filters are designed for extended service. They do not require normal scheduled maintenance. Filters should only be replaced if a diagnostic procedure indicates to do so.

The combination fuel filter/pressure regulator is located in front of the fuel tank and above the rear axle. It is transversely mounted to a chassis crossmember (left-to-right). The filter/regulator is equipped with 3 fuel line fittings (2 at one end and 1 at the other end). The single fitting facing the left side of the vehicle is the supply line to the fuel rail. The 2 fittings facing the right side of the vehicle are connected to the fuel tank. Of these 2 fittings, the fitting towards the front is used for fuel return to the fuel tank. The fitting towards the rear is a pressure line.

FUEL LEAK FROM CANISTOR LOCATED UNDER THROTLE BODY.It is not the fuel regulator. The part has a fuel line going into and out of it.The fuel line going into it seems to be part of the part.


That is the fuel pressure regulator, If you go to Auto Zone. they will have the replacement part and i believe it's around $65.00 and should take you no-more then 30 min to replace it if your good with common tools. Auto Zone will also have the step by step instructions for you to get the job done as to the dealer will charge around $200.00 to get the regulator replaced. What happens to the regulator is the diaphragm in the canister will fail and the gas will leak through, inspect the vacuum line to the regulator also to make sure there are no damages to the vacuum line since it's rubber. Good luck and when installing the new regulator, make sure you spray oil on the O-ring on the new regulator that goes in to the fuel injector rails.

Ase describe your where is the fuel pressure


If you look at the top of the upper intake manifold plenum with the air intake duct work off you will see 2 shiny fuel tubes that feed into the fuel meter body. The fuel meter body also has an electrical connector right in the middle of it. The pressure regulator is mounted on the side of that body. You'll have to remove the upper intake manifold manifold to replace it. Before you do that, be sure to bleed the pressure off the fuel system.
