Clips, O-rings, gaskets, hoses and other installation hardware are not specified as included in the company package record. Reuse only components that are confirmed serviceable and correct for your engine.

Installation Notes

  1. Disconnect the boat battery, shut off the fuel supply and allow the engine and fuel system to cool before starting work.
  2. Work in a well-ventilated area away from sparks, flames and other ignition sources.
  3. Label the existing fuel lines and any connected components before removing the original pump.
  4. Remove the original fuel pump and inspect the mounting surface, fuel lines and connectors for damage, contamination or deterioration.
  5. Install the replacement pump in the same orientation as the original and use the correct seals or gaskets for your engine.
  6. Reconnect the fuel lines securely and confirm that the routing is not kinked or rubbing against moving or hot components.
  7. Prime the fuel system according to the engine service manual.
  8. Start the engine only after checking the installation, then inspect carefully for fuel leaks and abnormal operation.

Follow the Honda service manual for your exact engine model, torque specifications and fuel-system procedures. Professional installation is recommended when working on a marine fuel system.

Troubleshooting & FAQ

How do I confirm this pump fits my Honda outboard?

Confirm that your engine is a Honda Marine 4-stroke BF25A, BF30A, BF40A, BF45A, BF50A or BF75A/BF90A application listed above. Compare the complete engine model and the original pump’s reference number with the part-number matrix before ordering. Year and serial-number coverage is not specified, so verify those details with your service information when applicable.

What reference numbers are associated with this pump?

The listed Honda reference numbers are 16700-ZV5-000, 16700-ZV5-003 and 16700-ZW1-004. The listed aftermarket reference is 18-7334. These numbers are provided for identification and compatibility comparison; this listing is for an aftermarket replacement, not a genuine Honda part.

What are common signs of a failing mechanical fuel pump?

Possible symptoms include hard starting, engine hesitation, sputtering, stalling, reduced power or inconsistent operation under load. These symptoms can also result from restricted fuel lines, a blocked filter, contaminated fuel, ignition faults or other engine problems. Diagnose the complete fuel system before replacing the pump.

Can I install this pump myself?

Installation may be possible for an experienced marine technician or mechanically qualified owner, but fuel-system work presents fire, leakage and engine-safety risks. Use the correct service manual and have the work performed by a qualified professional if you are unsure.

Is this an OEM Honda part?

No. This listing is for an aftermarket replacement fuel pump assembly. Honda names and part numbers are shown only as application and reference information.

Does the package include clips, O-rings or a gasket?

The company record identifies this product as a single fuel pump assembly and does not specify clips, O-rings, gaskets or other additional components as included. Confirm the required installation hardware for your engine before beginning the repair.

Safety & Important Information

  • Verify the complete engine model, stroke, horsepower and original pump reference before purchase.
  • Do not rely on horsepower alone to confirm fitment; model suffixes and engine configuration matter.
  • Do not install a part if the mounting pattern, ports, connectors or physical dimensions differ from the original.
  • Relieve fuel-system pressure and prevent spills during removal and installation.
  • Inspect all fuel-system components and repair leaks before operating the boat.
  • This is an aftermarket replacement, not an OEM Honda component.
