How to Replace Your Truck's Diesel Fuel Filter
All diesel trucks come installed with a diesel fuel filter to extract the best performance out of their engine by supplying clean and filtered fuel into the combustion cylinders. For any diesel engine, the primary equipment of defense to outside dust, dirt and other contaminants entering the combustion cylinders from the fuel tank is the fuel filter. A high-quality diesel fuel filter is able to stop particles up to size of 1 micron coming with the diesel. With time, the filtered particulate matter builds up and gets accumulated on the fuel filter. It can lead to clogging of the fuel injector points or combustion cylinder valves. Thus, it is essential to clean or replace your truck’s diesel fuel filter after a certain period.
Step 1 – Locate the Fuel Filter
Open the hood of the truck’s engine and use the owner’s manual to read the diagram to locate the position of the diesel fuel filter. Generally, the fuel filter is located on the rear side of the diesel engine.
Step 2 – Remove Plugs
There are sensors attached at the bottom of the fuel filter, which guide the flow of the diesel through the filter. Remove the wire plugs of the sensors.
Step 3 – Drain Extra Diesel
Place the pan beneath the fuel filter and open the drain valve of the filter so that any remaining extra fuel is drained-off immediately.
Step 4 – Open the Fuel Filter
Now, open the lid of the fuel filter socket. Use the fuel filter tool to unscrew the old fuel filter. Make sure to check for the o-ring. While removing the fuel filter bring out the socket straight up without tilting. Removing the filter will ooze out more fuel in to the pan.
Step 5 – Place New Fuel Filter
After removing the old filter, now place the new diesel fuel filter into the socket. Put some diesel into the fresh filter before installing. Place the o-ring on the socket only after greasing it a little. Put the filter socket back in its position.
Step 6 – Close the Drain Valves
It is time to close the diesel fuel filter drain valves. Use the fuel filter tool to tighten the screws. Place the wire plugs back on the sensors of fuel filter.
Step 7 – Check for Leakage
The final step in replacing the diesel fuel filter of a truck is to switch on the engine and check for fuel leakage on the joints. Do apply some grease or a few drops of oil on the seal. If there is any kind of leakage, immediately ask for professional help.
