WHERE IS THE FUEL FILTER? - 2003 Lincoln Navigator

Fuel Filter
The fuel filter is contained in the fuel sender assembly inside the fuel tank. the paper filter element of the fuel filter traps particles in the fuel that may damage the fuel injection system. The fuel filter housing is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. There is no service interval for fuel filter replacement.

2 of them........First Fuel Filter

One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.

Second Fuel Filter Location

The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.

Fuel Filter Types

The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.

The fuel filter is contained in the fuel sender assembly inside the fuel tank. the paper filter element of the fuel filter traps particles in the fuel that may damage the fuel injection system. The fuel filter housing is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. There is no service interval for fuel filter replacement.

IMPORTANT: This vehicle has a lifetime fuel filter built into the fuel sender inside the tank and thus is not serviceable separately. The fuel filter is not a replaceable part.

your diesel engine should have a center bolt holding fuel filter it in place.you place drain pan under fuel filter when you remove top center bolt while holding fuel filter then remove old fuel filter then take new fuel filter add few ounces clean diesel fuel in new fuel filter lubricate gasket new fuel filter cartridge then install new filter crank engine check for leaks.

Fuel Filter REMOVAL & INSTALLATION CAUTION
NEVER SMOKE WHEN WORKING AROUND OR NEAR GASOLINE! MAKE SURE THAT THERE IS NO ACTIVE IGNITION SOURCE NEAR YOUR WORK AREA! 1970-83 Carbureted Engines The fuel filter is located on the right inner fender in the engine compartment. It is a disposable cartridge type.

1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner.
2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipes.
3. Pull the filter from the clip and discard.
4. Install the new filter into the clip. Push the hoses onto the filter pipes, and slide the clamps back into position. Start the engine and check for leaks. Fig. 1: Fuel filter - 1970-79

1984-86 Carbureted Engines The fuel filter is located on the inside of the frame above the left rear spring front shackle. Changing the filter is VERY awkward. Since it is in-line and below tank level, fuel will pour from the fuel lines when they are disconnected from the filter. The only way of preventing this, is to siphon all of the gasoline from the tank before replacing the filter. Another possible method is to clamp and plug the fuel line, but this is not recommended because of the danger of leaking fuel or damage which could occur to the fuel line when clamped. It would, therefore, be a good idea to run the tank almost dry before changing the filter. Once the tank is dry, disconnect the fuel lines at the filter, unbolt the old filter and install a new one. Reconnect the fuel lines, fill the tank, start the engine and check for leaks. Fig. 3: Fuel filter - 1984-86

Fuel Injected Engines WARNING
Never attempt to remove the fuel filter without first relieving the fuel system pressure!

1. Release the fuel pressure from the fuel line as follows:
   1. Remove the fuel pump fuse at the fuse box.
   2. Start the engine.
   3. After the engine stalls, crank the engine two or three times to make sure that the fuel pressure is released.
   4. Turn the ignition switch OFF and reinstall the fuel pump fuse.
2. Loosen the hose clamps at the fuel inlet and outlet lines then slide each line off the filter nipples.
3. Remove the fuel filter.
4. Replace the fuel filter. Always be sure to use new hose clamps. Fig. 7: Fuel filter - 1986-88 VG30i
