How Often to Change Fuel Filter on 6.7 Powerstroke – Ultimate Guide

Of all engine components, none is more important than the much-neglected fuel filter. Without it, fuel cannot pass through any portion of the engine from injectors to cylinders ensuring that they deliver only clean air and fuel to the combustion process.

Here is a Step by step instructions on how to change the fuel filter on your Powerstroke 6.7L

Step 1. Use a fuel pressure gauge, safety glasses, and gloves to verify there isn’t pressure in the system. Be careful of fuel spills from this point forward as it is very slippery when combined with grease or oil. It can easily lead to fire and/or electrical shock if you are not careful.

Step 2. Open the engine hood of your F250 and locate the fuel filter. It is nestled neatly above one of the engine’s front wheels, to its left side. You will probably need a wrench to remove it from its holding area.

Step 3. Locate and disconnect the negative battery cable from its post using a wrench. or any other tool.

Step 4. Use a socket wrench to remove the fuel filter’s mounting nuts. Remove it from its holding area and place a clean, dry cloth over its neck to contain any small pieces that may come off when you pry the rest of its body away from its base mounted on top of the engine.

Step 5. Use a rag to wipe off excess traces of fuel from the area where it was located, then place it in an aluminum can with all the parts contained within it.

Step 6. Immediately replace the fuel filter with a new, quality aftermarket replacement. Be careful to follow directions closely and use good judgment when choosing your fuel filter replacement.

Step 7. Re-install the fuel filter into its holding location above one of the F250’s wheels after inspecting it for any missing or broken components. Tighten its mounting nuts gently using the socket wrench, then reconnect its negative battery cable.

Step 9. Open your engine hood and use a clean rag to wipe off excess dirt from its front side before driving it away from its parking spot. This will prevent cracked or damaged windshields if they are present on your vehicle.

Step 10. Let your F250 idle for about ten minutes to ensure that it has adequate fuel in storage until its new fuel filter is up and running at full capacity. After that drive your truck under twenty miles per hour for the first hour of driving after installation to allow time for the pump inside it to prime itself with fuel from the main tank.

Important Signs that Indicates a Need to Change Fuel Filter

Several signs indicate a bad fuel filter in your Powerstroke 6.7L engine and they include:

1.Your truck’s performance is noticeably affected while at idle or driving since it usually consumes more fuel than usual when this problem occurs. This is caused by dirty liquid passing through the pump into the tank during delivery to the injectors, causing them to misfire and drain your truck’s fuel filter.

  1. Your F250 is hard to start after it has been parked for several hours or even a full day since its idle speed drops when this happens. You notice that your truck starts to run roughly when you accelerate after you have been sitting in traffic for a long time and this could lead to poor fuel economy, stalling, hard starting, or RPM spikes.
  2. Your truck suddenly and rapidly loses power when you are driving it at cruising speed or accelerating up a steep hill. The truck runs erratically and is difficult to steer when it is idling. This could cause the truck to stall in
  3. You notice an unpleasant odor coming from inside of your F250’s cabin that smells like rotten eggs. This could be the result of high sulfur levels in your fuel.
  4. Your 6.7 Powerstroke engine makes a variety of sounds that are not normal. It could make a clicking or pounding sound when you accelerate, brake, go over bumps, or drive at highway speeds.
  5. You will notice that your F250 takes a long time to accelerate and has trouble climbing hills. This is an indication that you need a new fuel filter because the old one is not able to deliver the right amount of fuel demanded by your Powerstroke 6.7L engine.
