Best Practices to Avoid Contamination and Failure of a New Fuel Pump

IMPORTANT: Failure to clean the fuel tank and install a new strainer may allow contaminants to enter the pump and void the warranty. Contamination is the leading cause of fuel pump failure.

  1. Rust
    1. Can develop in a fuel tank from condensation produced through normal temperature changes.
    2. Will develop at a faster rate if the tank is habitually kept at low levels.
    3. Will develop in a tank that was not treated properly during the manufacturing process.
    4. Will develop in a tank that has been physically damaged (bent, crushed, or scraped).
  1. Dirt
    1. Can get into the vehicle’s tank if the cap is missing, not tightened or the wrong cap is used.
    2. Can get into the vehicle’s tank if the vent tube is damaged.
    3. Cannot be prevented by “White box” fuel filters with rubber or plastic internal components. Fuels with methanol or ethanol additives can erode a filter if it is not made with the proper materials.
    4. Can return to the tank through the return system.
    5. Can get into the vehicle’s fuel tank through contaminated fuel pumped from service station tanks. 
  1. Strainers
    1. NEVER reuse a strainer. Failure to properly install the new strainer will void your warranty. 
    2. The new strainer should always be installed onto the pump by hand and never pounded onto the pump. Strainers should be pushed straight onto the fuel inlet by hand. 
    3. Do not use a screw-on motion, hammer on the strainer or press the strainer against hard surfaces to install. Hand pressure should be sufficient. 
    4. Using a screw-on motion will cut the pump inlet and deposit pieces of the inlet housing into the strainer, which will cause pump failure. 
    5. Pounding the strainer onto the pump can cut a hole in the strainer, allowing large pieces of debris to enter the pump. Driving a strainer can also break internal nylon components contained inside the strainer. 
    6. Hammering or pounding strainers may break vanes from pump impellers, which fall into the strainer. Once the pump starts running, this debris enters the pump, and will cause immediate failure. If any of the above situations occur, the pieces can fall from the damaged pump inside the strainer. 
    7. If a strainer is reused, the new pump can draw debris from the previous pump failure from the old strainer, causing immediate failure of the new pump.
  1. Best Practice:
    1. Don’t drive repeatedly with a nearly empty gas tank. It can burn up your fuel pump since the pump relies on the gas flowing through it to cool it.
    2. Keep the gas cap tight. This helps keep dirt out of the tank and keeps evaporative emissions low.
    3. Regularly inspect the gas cap’s rubber flange for cracks and breaks. 
    4. Always run a good quality fuel.
    5. Use fuel with the recommended octane level for your vehicle.
    6. Have your fuel filter checked regularly and replace it if necessary (typically every two years or 30,000 miles). Follow the schedule in your vehicle owner’s manual.
    7. Regularly check your fuel hoses and lines for cracks and leaks.
    8. The occasional use of a quality fuel additive will help keep your fuel system clean and protect the injectors from clogging. 
    9. If you ever replace your fuel pump, make sure you have the tank cleaned.

Fuel Pump Assembly Float Arm Assembly Instructions

Please note the float arm is not installed on the fuel pump module (FDM). It must be mounted to  the fuel level sensor properly before the installation of FDM in the fuel tank.  

WARNING: 

Warning: All components must be handled carefully. Any damage, improper installation will affect the  accuracy of the fuel level reading. Damaged parts due to improper installation will void warranty. 

ASSEMBLE FLOAT ARM  

1. Insert the float arm into the pivot hole of the fuel level sender. 

2. Carefully push on the float arm until it snaps into the fuel level sender (refer to image).

IDENTIFY COMPONENTS: 

1. Pivot hole 

2.Float arm holder
