Moeller Mercury Fuel Connectors: Bayonet vs 2-Prong Clip

Mercury outboard fuel hoses have used different quick-connector profiles. The Moeller 033485-10 is a female bayonet-style fitting, 033486-10 is a tank-side female two-prong clip, and 033482-10 is a larger two-prong engine-side connector. All listed items take 3/8-inch-inside-diameter hose, but their mating fittings are not identical.

MPN Component Location Connection size and style
033485-10 Female bayonet hose coupler Hose to compatible bayonet fitting ⅜-inch hose I.D.; bayonet
033486-10 Female tank-side clip coupler Hose at fuel-tank side ⅜-inch hose I.D.; two-prong clip
033482-10 Female engine-side clip coupler Hose at outboard engine side ⅜-inch hose I.D.; large two-prong clip
Key fit distinction: Bayonet and clip connectors must not be mixed. Moeller 033485-10 uses a female bayonet-style coupling; 033486-10 is a female two-prong tank connection; and 033482-10 is a large two-prong engine-side connection. Their shared 3/8-inch hose size does not establish coupling interchangeability.

Replacement selection checklist

  1. Identify whether the failed component is screwed into the tank, attached to the hose at the tank side, or attached to the hose at the outboard engine side.
  2. Match the exact connector profile and latch style to the original mating half. Brand and approximate model year are not proof of fit.
  3. Measure the fuel-hose inside diameter and choose the corresponding 5/16-inch or 3/8-inch barb, or the correct 1/4-inch NPT threaded tank fitting.
  4. Inspect connector seals, retaining clips, damaged hose and any evidence of fuel leakage before installing a replacement.
  5. Use approved marine fuel hose and safe fuel-system practices, and verify every joint for leaks before operating the engine.
