Pulse comes through the mounting base, not through a third nipple. Current BRP-style number is 0438556 (written 438556 without the leading zero). The table lists the predecessor chain (388268, 385781, 433387, 432451 and related). Compatible with the Johnson \/ Evinrude HP groups in the fitment table, from older 33 \/ 40 HP late-1960s rows through 1990s 20–55 HP twins and larger 80–140 HP groups. Aftermarket catalogs that only say 25–55 HP 1976–89 are a subset — match the stamp. It is not an electric pump, not a 3-nipple external-pulse pump, and not a filter cartridge.\u003c\/p\u003e\n\u003ch3\u003eSigns yours is due\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePre-1990 Johnson \/ Evinrude 2-stroke with no VRO starves at cruise; the bulb stays firm — 2-port block-pulse valves are tired.\u003c\/li\u003e\n\u003cli\u003eFuel weep at the flange gasket (pulse through the base) rather than at a third nipple you do not have.\u003c\/li\u003e\n\u003cli\u003eYou counted nipples: two ports on the body, pulse through the pad.

Years run roughly 1968–1998 depending on HP. Serial is often not listed. 25 HP is the trap: some 25 HP use this 2-port 438556, later 25 HP use 3-nipple 438555. Count ports and read the stamp.

Compare port layout to the new body before you force hoses on. Fit a new flange gasket with the pulse hole open; a 180° gasket is a common miss and the engine will not pick up fuel.
