How to Replace a Fuel Filter on a 1999 Dodge 1500

The fuel filter on the 1999 Dodge 1500 requires a different replacement process than on most Dodge Rams from other model years. The function of the fuel filter on the Dodge Ram is to filter any sediments from the gas before the gas reaches the fuel injectors and the engine. The gas is pumped out of the gas tank by the fuel pump and into the fuel filter. Once that the fuel filter traps the sediments, the clean fuel then travels to the engine.

Park the 1999 Dodge 1500 in a level working area and open the hood.

Locate the fuel filter that is mounted near the rear of the driver's side of the firewall. The fuel filter is a black canister housing that holds the fuel filter inside of it. There will be a drain handle attached near the fuel filter housing with a small rubber tube. Place the catch pan under this tube and turn the handle to drain the gas from the fuel-filter housing.

Remove the lid to the fuel-filter housing with the ratchet and socket. Turn the lid counterclockwise to loosen and remove.

Pull the fuel filter out of the housing and discard it into the catch pan. Then, slide the new fuel filter into the housing. Also replace the canister lid O-ring with the new O-ring that comes with the new fuel filter.

Put the lid back onto the fuel-filter housing and tighten down with the ratchet and socket. Remove the fluid catch pan from the engine compartment.

Turn the ignition key on and off four times to prime the canister with fuel. Then, crank the engine on the fourth turn of the ignition. Let the engine run for about 30 seconds and then turn the engine off.

Inspect the fuel-filter housing lid for leaks and close the hood.
