Product Details
This replacement female fuel line quick-disconnect connector is intended for compatible Mercury and Mariner outboard fuel systems. The connector is identified as a 3/8-inch fuel connector and is designed to mate with the corresponding tank connector in applications using the matching quick-connect configuration.
It replaces Mercury Marine part numbers 22-13563A3 and 22-13563Q3. Sierra cross-reference information identifies the equivalent reference as 18-8076. Confirm the connector style, hose size, mating connector and engine serial-number range before ordering.
- Product Type: Female fuel line quick-disconnect connector
- Connection Size: 3/8 inch
- Fuel System: Outboard fuel line application
- Reference Relationship: Mates with the compatible tank connector configuration
Part Number Matrix
These references are supplied for identification and cross-reference purposes. Verify the original connector and application before installation.
| Brand | Part Number | Reference |
|---|---|---|
| Mercury Marine | 22-13563A3 | Replaced reference |
| Mercury Marine | 22-13563Q3 | Replaced reference |
| Sierra | 18-8076 | Cross-reference |
Engine & Model Compatibility
Fuel connectors are application-specific. Compatibility should be confirmed by matching the original part number, connector shape, hose connection and engine serial-number range. A general horsepower range alone is not sufficient to establish fitment.
The catalog relationship verified during research identifies Mercury part number 22-13563Q3 in the fuel tank and line assembly for the following application:
| Brand | Model | Rated HP | Stroke | Serial Number | Part Number | Catalog Position |
|---|---|---|---|---|---|---|
| Mercury | 25 H.P. Lightning, 3-cylinder, international model | 25 | Not specified | 0E288000 & Up | 22-13563Q3 | Fuel tank and line assembly, 6.6 gallon; reference 12 |
Other Mercury and Mariner applications may use this reference, but they are not confirmed here. Do not assume fitment for all 4–40 HP engines, all 2-stroke or 4-stroke models, Force engines or EFI models without checking the specific application.

Hose, clamps, tank connectors and other fuel-system components are not included unless separately stated for the selected product.
Installation Notes
- Turn the engine off, disconnect the ignition source and shut off the fuel supply before servicing the fuel system.
- Allow the engine and fuel system to cool. Work in a well-ventilated area away from flames, sparks and other ignition sources.
- Place an approved container or absorbent material beneath the connection and relieve fuel-line pressure according to the engine manufacturer’s procedure.
- Disconnect the existing quick connector and inspect the hose, retaining features and mating connector for cracks, wear or damage.
- Confirm that the replacement connector matches the original 3/8-inch connector and the specified Mercury reference.
- Attach the connector to the fuel hose using a suitable marine fuel-line clamp where required. Do not reuse damaged clamps or deteriorated hose.
- Connect the fitting to its matching mating connector until it is fully seated and securely retained.
- Prime the fuel system and inspect all connections for leaks before starting the engine. Stop immediately if any leakage is found.
Troubleshooting & FAQ
How do I confirm that this connector is correct for my engine?
Compare the original connector, connector size, mating arrangement and stamped or listed part number. The principal references for this listing are Mercury 22-13563A3 and 22-13563Q3, with Sierra 18-8076 as a cross-reference. Also verify the engine model and serial-number range.
Is this connector male or female?
This listing is for the female fuel line connector. The mating connector must have the corresponding male or compatible quick-connect configuration required by the specific fuel system.
What size connector is this?
Catalog information identifies this connector as 3/8 inch. This refers to the listed connector size and should not be interpreted as a universal hose or thread specification for every application.
Is this a tank-side or engine-side connector?
The available catalog information identifies it as a fuel connector used in a fuel tank and line assembly, but it does not establish one universal installation side for every application. Match the original connector and mating component rather than relying only on a tank-side or engine-side description.
What are the signs that a fuel connector needs replacement?
Fuel odor, wetness or leakage around the connection, cracking, brittleness, damaged retaining features, difficulty priming the fuel system or an insecure connection can indicate that inspection or replacement is required.
Can I use this with every Mercury or Mariner outboard?
No. Fuel connectors vary by model, serial number, hose size and mating design. The listed part-number references and a confirmed application should be matched before purchase.
Is this an OEM component?
This listing is for a replacement connector. Mercury Marine part numbers are shown as reference numbers for identification; the replacement should not be represented as a genuine Mercury-branded component unless the product packaging specifically states that it is OEM.
Safety & Important Information
- Fuel-system work involves flammable gasoline. Follow the engine manufacturer’s service instructions and applicable marine safety requirements.
- Verify the connector size, shape, part-number reference, mating connector and serial-number range before installation.
- Do not operate the engine if a fuel leak is present.
- Replace cracked, hardened or damaged fuel hose and clamps rather than installing a new connector onto unsafe components.
- Professional installation is recommended when the correct application or fuel-system procedure is uncertain.
