Pump Fails Prime

Updated 2 years ago by Juan Velez

This bulletin covers the following Champion Power Equipment models: All models that utilize quick-connect hoses.

Read instructions carefully and completely performing service.

  • To reduce the risk of injury, user must read and understand the operator’s manual before using this product.
  • DO NOT make any adjustments to the product without first stopping the engine and disconnecting the spark plug wire.
  • Burns from hot parts — let the engine cool completely before touching hot parts.
  • Injury from moving parts
  • To reduce the possibility of fire or explosion, be careful when working around gasoline. Keep cigarettes, sparks and flames away from all fuel‐related parts.

Remove the couple and re-wrap the threaded area of number eight with seven layers of Teflon tape. The tape must be wrapped clockwise as shown. (Pipe Dope can be used instead of Teflon tape.)

Reinstall the coupler to the pump flange and tighten it with a crescent wrench, combination wrench, pipe wrench, or adjustable pliers. Caveman tight is how tight we want it.

The suction hose and the hose clamp at the coupler must be tightened with a wrench or socket NOT just a screw driver.

The CAM locks must be fully locked and the levers completely drawn back towards the hose and seated.

The priming plug needs to be removed and the pump body must be filled to the top before starting the unit to pump.

Ensure the priming plug is secure before pump operation, if not secure the priming plug could be ejected and water or other liquids could be pumped through the top of the outlet flange.

Partially restricting the discharge hose by squeezing or bending it 90 degrees to the outlet flange can help reduce priming time; prime time can be as much as five minutes. If it is still not priming, remove the Quick Connector and put some water soluable grease on the big, black O-Ring that seals between the flange and the coupler.

There should not be any leaks between #1 and #2 or around #12 and #18. Any type of leak in these areas indicate a seal or O-Ring failure and a replacement part is required.
