The fuel filter is tucked into the inside of the frame rail on the driver's side

The fuel filter on a 1997 F350 Diesel is tucked into the inside of the frame rail on the driver's side. It is a canister filter, and the canister is black. The bottom of the canister can be unscrewed. The fuel filter is located underneath a cover, which can be removed by unscrewing two 13mm nuts.

The fuel filter should be replaced every 15,000 miles. To change the filter, first, open the drain port on the bottom filter housing. Then, go to the engine bay and remove the rear fuel line connection. The filter housing can be drained of diesel fuel by connecting a hose to the drain tube. Turn the lever on the drain tube clockwise to drain the fuel.

After draining the fuel, the cap can be removed using a strap wrench. The new fuel filter comes with two seals: a beveled gasket and an O-ring. The O-ring should be coated with diesel fuel and placed in the groove of the fuel filter. The new filter can then be inserted into the fuel filter housing. The beveled gasket should also be coated with diesel fuel and placed on the fuel filter housing, ensuring that the bevel is facing up. The cap can then be put back on and tightened using a strap wrench.

To prime the fuel system after changing the filter, turn the ignition on multiple times without starting the engine. This will pump the fuel up to the filter housing and return it to the tank.

Coat the beveled gasket with diesel fuel and set it on the fuel filter housing. The bevel goes up, and the flat side sits on the housing. Put the cap back on and tighten it with a strap wrench.

To prime the fuel system, turn the ignition on for 30 seconds and then switch it off. Repeat this operation six times in a row to purge any trapped air from the fuel system.
