Aynaxcol boat fuel connector for Mercury/Mariner outboards — 8M0182334 replacement, brass-finish durable seal, fits 4–175HP

Aynaxcol 8M0182334 is a direct-replacement boat engine fuel connector designed to restore a secure fuel line attachment on Mercury and Mariner outboard engines from 4HP up to 175HP.

This engineered fuel connector replaces part numbers such as 22-8M0148583, 15781A5 and related OEM references to provide a reliable connection between your fuel tank and outboard engine. Built with a blend of durable plastic and a brass exterior finish, the connector aims to withstand exposure to saltwater, vibration and routine engine movement while keeping fuel delivery steady. The single-piece package includes one connector so you can swap the worn or damaged part quickly and get back on the water.

How will this connector fit my Mercury or Mariner outboard?

The Aynaxcol connector was manufactured to match the mounting and hose interface used across many Mercury and Mariner models. It fits a broad range of small and mid-size outboards from 4HP to 175HP, covering common OEM part numbers for straightforward substitution.

• Direct-replaces 22-8M0148583, 8M0182334, 15781A5 and similar numbers.
• Compatible with Mercury/Mariner 4HP, 5HP, 6HP, 8HP, 9.9HP, 15HP, 20HP–70HP, 75HP, 90HP, 175HP.
• Designed for the same hose diameter and fitting style used on those outboards.

What materials and construction does the connector use?

The connector combines engineered plastic for internal sealing with a brass-finish exterior to resist corrosion and wear. This construction balances weight and resistance to marine elements while maintaining a solid attachment point for fuel lines.

• Inner plastic body for secure sealing and fuel compatibility.
• Brass-finished exterior for improved corrosion resistance and durability.
• Manufactured to withstand vibration and normal marine exposure.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone familiar with basic outboard maintenance: remove the old fuel connector, confirm hose sizes, and replace with the Aynaxcol connector. No special tools are typically required beyond standard pliers or hose clamps; always follow safety steps to avoid fuel spills.

• Remove fuel supply pressure or isolate the tank before starting.
• Use standard hose clamps and pliers for a tight, leak-free fit.
• Inspect fuel hose condition and replace if brittle or cracked.

Will this connector improve fuel delivery or engine performance?

Replacing a damaged or leaking connector restores the integrity of the fuel line, which helps ensure consistent fuel flow to the engine. While it does not alter engine tuning, a tight, correctly fitted connector reduces the risk of air ingress and leaks that can cause running issues.

• Prevents leaks that may interrupt fuel supply.
• Maintains a sealed connection to reduce air entry into the fuel line.
• Helps preserve normal engine operation by securing fuel delivery.

Who this is for: Boaters, marine technicians and weekend DIYers who own Mercury or Mariner outboards and need a dependable, OEM-compatible replacement fuel connector. It’s ideal if you’re replacing a corroded, cracked or leaking connector on engines from small 4HP motors up through larger 175HP models and want a simple swap that uses familiar hose clamps and installation steps.
