Genuine Yamaha Japan-built mechanical fuel pump with a robust molded upper housing and die-cast lower chamber, plus clearly cast IN/OUT flow markings. OEM-spec internal diaphragm/check-valves and exact fitment make it the most dependable choice for avoiding fuel leaks or fuel-starvation issues.

EMP 1399-39550 (China) is a near visual clone of the Yamaha pump, including matching IN/OUT placement and the center “2” casting mark, suggesting OEM-like geometry and fit. Its OEM-style tooling and gasketed two-piece construction make it the strongest aftermarket option here, with the main unknown being long-term internal rubber/valve material longevity versus the Japan OEM assembly.

ARCO FP010 (Taiwan) is not an OEM rebrand—the boxed IN/OUT casting details and exterior finish indicate different tooling and a different manufacturing source than Yamaha. It should function as a replacement, but the non-OEM design/source makes long-term diaphragm and valve durability less predictable than the OEM pump.

RATHER DISAPOINTING. I got an email yesterday saying my package had been delivered when actually it probably will not arrive until Monday!! somebody is not keeping their eye on the ball. But --- not a big deal,--- this is not a medical emergency, I would happily order from Crowley again. have a great summer
