🛠️ Pro Installation Tips

• Safety First: Ensure you are working in a well-ventilated area away from any sparks or open flames. Disconnect the negative battery terminal before starting to prevent any electrical mishaps.

• Clean the Area: Before removing the old pump, use compressed air or a brush to clear any dirt and debris from the top of the tank. Do not let contaminants fall into the fuel tank, as they can clog the new strainer instantly.

• Lube the Seal: Always use the new O-ring/gasket included. Apply a thin layer of clean fuel or silicone grease to the seal before installation. This ensures a proper seat and prevents the seal from pinching or tearing.

• Alignment is Key: Most Suzuki KingQuad fuel tanks have alignment marks. Ensure the pump assembly is oriented correctly so the fuel level float can move freely without hitting the tank walls.

• Prime the System: Do not start the engine immediately after installation. Turn the ignition key to the ON position for 5 seconds and back to OFF, repeating this 3-5 times. This primes the pump and builds up the necessary fuel pressure.

• Tank Condition: If your previous pump failed due to debris or "bad gas," we strongly recommend draining and cleaning the fuel tank before installing the new unit to prevent premature failure.

⚠️ Notice: Professional installation is highly recommended. Improper installation can lead to fuel leaks or inaccurate fuel gauge readings.

🔧 Tools Required

Most Suzuki KingQuad models will require these basic tools:

• Socket Set (8mm & 10mm): To remove seat/plastics and the fuel pump mounting bolts.

• Phillips Head Screwdriver: For body clips and panel removal.

• Needle-Nose Pliers: To safely release the fuel line quick-connect clips.

• Compressed Air or Soft Brush: To clean the tank surface before opening.

• Clean Shop Rags: To catch any residual fuel when disconnecting lines.

Issue	Possible Cause	Solution
Engine won't start	System not primed or air in lines.	Cycle the ignition Key ON/OFF 5 times to build pressure before cranking.
No "Humming" sound	No power to the pump.	Check the Fuel Pump Fuse and the Relay. Ensure the electrical connector is clicked in tight.
Fuel gauge is stuck/wrong	Float arm is obstructed.	The pump might be rotated slightly. Ensure the alignment marks on the pump and tank match perfectly.
Sputtering/Low Power	Clogged fuel line or old gas.	Inspect fuel lines for kinks and ensure you are using fresh, clean fuel.
Fuel leak at the top	Pinched O-ring or loose bolts.	Inspect the seal for tears. Ensure mounting bolts are tightened in a star pattern for even pressure.

 

💡 Final Expert Tip:

Before fully reassembling all the plastic bodywork, test-start the ATV and check for leaks around the seal and hose connections. It’s much easier to fix a minor seating issue while the tank is still exposed!
