Frequently Asked Questions (FAQ)

Q: How do I know if this fuel pump fits my outboard motor?

A: To ensure compatibility, check:

1.Engine Model & HP (e.g., "Johnson 25HP" or "Honda 50HP").

2.Original Fuel Pump Part Number (match numbers on your old pump).

3.Year of Manufacture (designs may vary by year).

If you are unsure,please contact us with these details for verification!

Q: What specifications should I compare when selecting a fuel pump?

A: Key measurements include:

1.Fuel Flow Rate (e.g., 20 GPH, 30 GPH).

2.Pump mounting style (bolt-on vs. bracket-mounted)

3.Mounting Bolt Pattern (hole spacing/alignment).

4.Inlet/Outlet Port Size (thread type and diameter).

5.Pressure Rating (e.g., 4-6 PSI for most outboards).

Q: Why must my fuel pump repair kit match the exact model?

A: Kits contain diaphragms, valves, and gaskets engineered for your pump’s design. Minor variations can lead to fuel delivery issues or leaks.

Q: How often should I service my outboard fuel pump?

A: Maintenance intervals depend on:
• Usage frequency (annual service for regular use)
• Fuel type (ethanol blends require more frequent checks)
• Environment (saltwater = more corrosion risk)
Recommended: Inspect annually and replace diaphragms every 2-3 years.

Q: What symptoms indicate I need a new fuel pump or repair kit?

A: Watch for:

1.Engine sputtering at high RPMs.

2.Difficulty starting or sudden power loss.

3.Fuel leaks around the pump housing.

4.Overheating due to lean fuel mixture.
