4. Configuració i instal·lació

Installation of the AEM 50-1215 fuel pump typically involves replacing an existing in-tank fuel pump assembly. Due to the complexity and safety considerations involving fuel systems, professional installation is highly recommended. Always ensure the vehicle's battery is disconnected and appropriate safety measures are taken when working with fuel.

4.1. Preparació

• Ensure the vehicle is on a level surface and the engine is cool.
• Desconnecteu el terminal negatiu de la bateria del vehicle.
• Relieve fuel system pressure according to the vehicle manufacturer's service manual.
• Access the fuel pump assembly, typically located under the rear seat or in the trunk area.

4.2. Removing the Old Fuel Pump

• Carefully disconnect the electrical connector and fuel lines from the existing fuel pump assembly. Use a rag to catch any residual fuel.
• Unscrew the large plastic retaining ring that secures the fuel pump assembly to the fuel tank.
• Gently lift the entire fuel pump assembly out of the tank, being careful not to damage the fuel level sender float arm.

4.3. Disassembling the Fuel Pump Assembly

• On a clean workbench, carefully disassemble the old fuel pump from its housing. This may involve releasing clips or tabs.
• Remove the old pre-filter and any rubber isolators or mounts.
• Disconnect the wiring from the old fuel pump. Note the polarity (positive/negative) for correct re-connection.

4.4. Installing the New AEM Fuel Pump

• Connect the new wiring harness to the AEM fuel pump, ensuring correct polarity (red to positive, black to negative).
• Install the new rubber isolators and mounts onto the AEM fuel pump.
• Attach the new pre-filter (sock filter) to the inlet of the AEM fuel pump.
• Carefully install the new AEM fuel pump into the existing fuel pump housing, ensuring all components are correctly seated and wires are routed without pinching.

4.5. Reinstalling the Fuel Pump Assembly

• Carefully lower the reassembled fuel pump unit back into the fuel tank, ensuring the fuel level sender float arm moves freely and is not obstructed.
• Install the new O-ring (if provided) and tighten the plastic retaining ring securely.
• Reconnect the fuel lines and electrical connector. Double-check all connections for tightness.
• Torneu a connectar la bateria del vehicle.

5. Instruccions de funcionament

After installation, perform the following steps to ensure proper operation:

• Turn the ignition key to the 'ON' position (without starting the engine) for a few seconds to allow the fuel pump to prime the system. Repeat this step 2-3 times.
• Check for any fuel leaks around the pump assembly and fuel lines.
• Start the engine and allow it to idle. Monitor fuel pressure (if a gauge is installed) and check for any unusual noises or leaks.
• Test drive the vehicle under various conditions to confirm proper fuel delivery and engine performance.

6. Manteniment

Regular maintenance helps ensure the longevity and optimal performance of your AEM fuel pump:

• Substitució del filtre de combustible: The pre-filter included with the pump should be inspected and replaced periodically, or if signs of clogging are observed. Consult your vehicle's service manual for recommended intervals for in-line fuel filter replacement.
• Qualitat del combustible: Always use high-quality fuel. Poor fuel quality can lead to premature wear and failure of the fuel pump.
• Inspecció del sistema: Periodically inspect fuel lines, connections, and the pump assembly for any signs of leaks, corrosion, or damage.

7. Solució De Problemes

If you experience issues with your fuel pump, consider the following troubleshooting steps:

• No Fuel Pressure/Engine Cranks but Won't Start:
  • Check electrical connections to the fuel pump for proper contact and voltage.
  • Verify the fuel pump fuse and relay are functioning correctly.
  • Assegureu-vos que hi hagi prou combustible al dipòsit.
  • Inspect the pre-filter for clogging.
• Low Fuel Pressure:
  • Check for restrictions in the fuel lines or a clogged fuel filter.
  • Inspect the fuel pressure regulator for proper operation.
  • Verify the fuel pump's electrical supply (voltage and ground).
• Excessive Noise from Fuel Pump:
  • Ensure the fuel tank is not running consistently low, as this can cause the pump to overheat.
  • Check for air leaks in the fuel system (e.g., loose connections, damaged O-rings).
  • Verify proper installation of rubber isolators to minimize vibration.

If troubleshooting steps do not resolve the issue, consult a qualified automotive technician.
