FAQs

This fuel pump is commonly used on Johnson and Evinrude outboards, and it is also cross-referenced under OMC, Sierra, and Mallory numbering. The most consistent fit information in the available references is for many 1976-1989 25-55 HP non-VRO models, though broader listings also place it on certain 20-140 HP Johnson/Evinrude applications. Because these engines were built across many years and fuel-system variations, the safest match is by your original part number and engine model rather than horsepower alone.
The title numbers are 438556 and 18-7352. Additional cross-reference numbers found in the available sources include 0438556, 385781, 388268, 394543, 395713, 382354, 398387, 398338, 432451, 433387, 9-35352, and 1399-07352. Some marketplace listings also associate this pump with 433390 and 385784, so if you are matching one of those numbers, confirm against your engine model before ordering.
Common symptoms include hard starting, the engine needing choke longer than normal, stumbling on acceleration, surging at mid-range, loss of top-end power, or the engine dying as throttle demand increases. On a mechanical outboard pump, a weak diaphragm or leaking check valves can reduce fuel delivery, especially under load. If the engine runs briefly when primed but then falls flat, the fuel pump is a common item to inspect.
On most Johnson/Evinrude outboards that use this style pump, installation is usually a straightforward bolt-on job. Typical tools are a screwdriver, a nut driver or small socket set, pliers for hose clamps, clean rags, and a container to catch any fuel drips. Plan on about 20-45 minutes if access is clear. Install the new gasket carefully, reconnect the fuel lines to the correct ports, and inspect the hoses while everything is apart.
Yes. A weak fuel pump can act a lot like a restriction elsewhere in the fuel system. Before or during replacement, inspect the fuel lines for cracking or softness, check the primer bulb, verify the tank vent is open, inspect the fuel filter, and look for air leaks at fittings. On older outboards, stale fuel and deteriorated hose material are common causes of poor fuel delivery, so replacing the pump alone may not solve the issue if contamination or line collapse is present.
Yes. This is a mechanical pulse-type outboard fuel pump used on specific carbureted Johnson/Evinrude applications. It is not a universal pump, and fit can vary by horsepower, year, and whether the engine uses a VRO-style fuel/oil system or a non-VRO setup. Available references specifically mention non-VRO applications for some 25-55 HP engines, so engine model verification is important even when the horsepower seems to match.
