Product Overview

A four-stroke outboard that starts on primer fuel but starves at speed, loses power under load, or leaks fuel from the pump area may have a failed diaphragm pump. This replacement restores low-pressure fuel transfer on compatible engines after the lines, tank vent, filter, and pulse source have been checked.

Marine fuel work demands care. Any fuel smell, cracked hose, or leaking fitting must be corrected before the engine is run.

  • Mechanical diaphragm-style fuel pump
  • For select Mercury/Mariner four-stroke outboards

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Frequently Asked Questions

Q: Can this pump cause power loss at wide-open throttle? A: Yes, if it cannot supply enough fuel, but tank venting, filters, hoses, and carburetors must also be checked.

Q: Does it fit every Mercury 40 HP? A: No. Verify the exact engine serial number and original pump reference.

Q: Is a fuel leak safe to test on the water? A: No. Repair leaks completely before running the engine.

Q: Why does the engine run after squeezing the primer bulb? A: That can point to a supply-pump or upstream restriction issue, but testing is still required.
