4. Installation Instructions
The aFe POWER PROGUARD Fuel Filter is designed as a direct stock replacement. While installation can be straightforward for experienced individuals, professional installation is recommended to ensure proper fitment and to avoid potential fuel system issues.
General Installation Steps (Consult Vehicle Service Manual for Specifics):
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and ensure the engine is off and cool. Disconnect the negative terminal of the battery.
- Locate the Fuel Filter: Refer to your vehicle's service manual to identify the location of the existing fuel filter. This filter is often found in the engine bay or along the chassis.
- Relieve Fuel Pressure: Follow your vehicle's specific procedure to safely relieve fuel system pressure. This typically involves removing a fuel pump fuse or relay and cranking the engine.
- Disconnect Fuel Lines: Carefully disconnect the fuel lines from the old filter. Be prepared for some fuel spillage and have a drain pan ready. Use appropriate tools to prevent damage to fuel line fittings.
- Remove Old Filter: Detach the old fuel filter from its mounting bracket.
- Install New Filter:
- Ensure the new aFe POWER PROGUARD Fuel Filter is oriented correctly according to flow direction (if indicated).
- Lubricate the new O-ring with a small amount of clean diesel fuel or appropriate lubricant before installation to ensure a proper seal.
- Secure the new filter into its mounting bracket.
- Reconnect Fuel Lines: Reattach the fuel lines to the new filter, ensuring all connections are secure and leak-free.
- Prime the Fuel System: Reconnect the battery. Turn the ignition to the "ON" position (without starting the engine) for a few seconds, then turn it off. Repeat this several times to allow the fuel pump to prime the system and remove air from the lines. Check for leaks.
- Start Engine and Inspect: Start the engine and carefully inspect the new filter and connections for any signs of leaks. Allow the engine to run for a few minutes to ensure proper operation.
