Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: Start by checking your engine's model and year against the compatibility chart above. It is also critical to verify this part visually against your old one and cross-reference the OEM part numbers (16700-ZV5-003, 16700-ZW1-004). Be aware that some BF40D and BF50D models may require a different pump (16700-ZZ5-003).

A: Signs of a faulty fuel pump include engine bogging down under load, difficulty starting, rough idling, or a noticeable loss of power. These issues occur when the pump can no longer supply adequate fuel pressure to the carburetors.
