Step 1: Relieving Fuel Pressure

• Loosen and remove the valve cap.

• Push down on the valve to release the fuel pressure. Hold it for a few seconds (5-10).

• Put the cap back on the valve.
  
  
  

Step 2: Preparing the Truck

• Avoid lifting the truck with the exhaust on the passenger side to prevent damage. Use quality jack stands to support the truck at the recommended corners as per the owner's manual.
  
  
  

Step 3: Accessing the Fuel Filter

• Locate the fuel filter on your truck.

• Identify the two safety clips on either side of the filter.

• Pull each safety clip towards the filter to release it from the locked position.
  
  
  

Step 4: Releasing the Fuel Lines

• Use your finger to pull each safety clip towards the filter and slide it back.

• Use a fuel disconnect tool to release the springs on the fuel lines. Pull the tool away from the filter while oscillating it if necessary.

• Position a pan beneath the filter to catch any fuel.

• Gently pull the fuel lines off the filter one by one, allowing the fuel to drain into the pan.
  
  
  

Step 5: Removing the Filter

• Carefully walk the filter toward the front of the truck.

• Roll back on the bracket and remove the filter from the bracket.
  
  
  

Step 6: Installing the New Filter

• Check the direction of flow indicated by an arrow on the new filter. It should face towards the front of the truck.

• Position the new filter into place by aligning it with the bracket.

• Push the filter down until it bottoms out with the tab on the bracket.
  
  
  

Step 7: Reconnecting the Fuel Lines

• Slide the fuel lines back into their original positions on the new filter.

• Ensure an audible click to confirm that each line is securely engaged.

• Double-check the connections by gently pulling back on each line.
  
  
  

Step 8: Securing Safety Clips

• Bring the safety clips back towards the filter.

• Hook the clips onto the underside of the fuel lines and push them in any direction until they snap back onto the fittings.
  
  
  

Step 9: Clean Up

• Remove the drain pan and wipe the filter and surrounding area clean.

• Bring the safety clips back towards the filter, securing them in place.

• Wipe up any spilled fuel to clean up the work area.
