Preparing for the Change: Finding the Fuel Filter
The Ford 6.7 fuel filter is located on the driver’s side of the engine, near the firewall. It’s a cylindrical-shaped filter housing with a black plastic cover. You’ll find two fuel lines connected to the housing.
Step 1: Relieve Fuel Pressure
Before you can remove the fuel filter, you need to relieve the pressure in the fuel system. This is an essential safety step to prevent fuel from spraying out and causing a potential fire hazard.
- Locate the Fuel Shutoff Valve: The fuel shutoff valve is typically located on the driver’s side of the engine, near the fuel filter. It’s a small lever that you can pull to shut off the fuel supply.
- Turn Off the Engine: Make sure the engine is completely off.
- Pull the Fuel Shutoff Valve: Pull the fuel shutoff valve to the “off” position.
- Start the Engine: Start the engine and let it run for a few seconds. This will deplete the fuel in the lines.
- Turn Off the Engine: Turn off the engine again.
Step 2: Disconnect the Fuel Lines
Now that the fuel pressure is relieved, you can disconnect the fuel lines from the filter housing.
- Use the Fuel Line Disconnect Tool: Insert the fuel line disconnect tool into the fuel line connector and push down to release the line.
- Disconnect Both Fuel Lines: Repeat this process for both fuel lines.
Step 3: Remove the Old Fuel Filter
With the fuel lines disconnected, you can now remove the old fuel filter.
- Loosen the Filter Housing Bolts: Use a wrench to loosen the bolts holding the filter housing in place.
- Remove the Filter Housing: Once the bolts are loose, carefully remove the filter housing from the engine.
- Remove the Old Fuel Filter: The old fuel filter should now be accessible. Use the fuel filter wrench to unscrew it from the housing.
Step 4: Install the New Fuel Filter
Installing the new fuel filter is the reverse process of removing the old one.
- Clean the Filter Housing: Before installing the new filter, make sure the filter housing is clean and free of any debris.
- Install the New Fuel Filter: Screw the new fuel filter into the filter housing. Be careful not to overtighten it.
- Reinstall the Filter Housing: Place the filter housing back on the engine and tighten the bolts securely.
Step 5: Reconnect the Fuel Lines
With the new filter installed, you can now reconnect the fuel lines.
- Connect the Fuel Lines: Insert the fuel lines back into the connectors on the filter housing and push down to secure them.
- Tighten the Fuel Line Connectors: Ensure the fuel line connectors are securely tightened.
Step 6: Turn the Fuel Shutoff Valve On
Now that the fuel lines are reconnected, you can turn the fuel shutoff valve back on.
- Pull the Fuel Shutoff Valve: Pull the fuel shutoff valve to the “on” position.
Step 7: Start the Engine and Check for Leaks
Start the engine and check for any fuel leaks. If you see any leaks, immediately shut off the engine and re-tighten the fuel lines or filter housing bolts.
Final Touches: The Engine’s New Lease on Life
After successfully changing the fuel filter, your Ford 6.7 Power Stroke engine will enjoy a renewed lease on life. You’ll likely experience a smoother idle, improved fuel economy, and a more responsive engine.
