Which pump is this?

MECHANICAL LOW-PRESSURE DESIGN: This engine-mounted diaphragm pump uses a plunger, diaphragm, return springs and check valves to move fuel from the boat tank toward the carburetor, matching the official Yamaha FUEL 2 exploded view and the Suzuki FUEL PUMP figure for this part family. It is not an electric in-tank pump and not a high-pressure EFI pump. Similar-looking pumps from other Yamaha families are not interchangeable.

Signs yours is due

REPLACE THE COMPLETE PUMP: Intended as a complete-pump replacement for symptoms such as stalling when throttle is applied, a primer bulb that will not stay firm, fuel starvation under load, external fuel seepage from the pump body or gasket, after the rest of the fuel path has been checked. The package contains one fuel-pump assembly only; fuel filter, hoses, clamps, mounting bolts, gaskets and repair-kit parts are not included unless pictured by the seller.

Will it fit?

COMPATIBLE FITMENT: Compatible with select Yamaha F4 and F6C four-stroke outboards listed in official catalog records for the 67D-24410 and 6BX-24410 families, select Suzuki DF4, DF5 and DF6 P01-generation models covered by the manufacturer-issued parts catalogue, and select Johnson 4-6 HP four-stroke models listed for 5033371 and 5037518. Match the original pump number and engine model before ordering. Not for two-stroke engines, Yamaha F6A, or electric high-pressure fuel systems.

Every row is from this SKU fitment workbook. Match the number stamped on the pump you remove. Same horsepower name shipped different pumps.

Install

INSTALL WITH PART-NUMBER DISCIPLINE: Work in a ventilated area away from ignition sources, label the inlet and outlet hoses, compare the check-valve order and port orientation with the removed pump, renew damaged seals, use the engine manual's fastener torque, prime the line and inspect for leaks. If the old pump number cannot be read, send the engine model and a photo of the original pump before purchase.
