Current BRP-style number is 0438559 (written 438559 without the leading zero). Service \/ package number 0765591 (765591) is the same pump in a different bag. The table also lists the long predecessor chain (381600 through 433390 and related). Compatible with the Johnson \/ Evinrude HP groups in the fitment table (examples include 6 \/ 8 HP 1987 rows, 25 \/ 35 HP mid-1990s commercial, and older 50–100+ HP groups). It is not an electric pump and not an inline fuel-filter cartridge.\u003c\/p\u003e\n\u003ch3\u003eSigns yours is due\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBig 2-stroke Johnson \/ Evinrude surges or starves at cruise; squeezing the bulb keeps it alive — external-pulse pump valves are lazy.\u003c\/li\u003e\n\u003cli\u003eFuel spray from a nipple or a cracked plastic body on a 3-port pump mounted on the block \/ cowl area.\u003c\/li\u003e\n\u003cli\u003eOn V4 \/ V6 motors that run two pumps: one bank goes lean.

Years run from late-1960s blocks through 1990s commercial 25 \/ 35 HP. The catalog often groups by horsepower name with long model lists (BE25, E6R, 70 HP 1974–1983, and so on) and does not always give serial ranges. Match 438559 \/ 0438559 on the pump you remove.
