Troubleshooting & FAQ

How do I know if this fuel pump fits my Honda outboard?

This pump is designed for Honda BF series 4-stroke outboards from 25 HP to 90 HP. The best way to confirm fitment is to check your original part number against the direct replacements listed (16700-ZV5-003, 16700-ZW1-004).
