Mercury fuel connector male flywheel attachment – code: 52.805.80 – Osculati

Mercury fuel coupling with male quick connect (Osculati 52.805.80)

The’Mercury fuel coupling with male quick connect Osculati, identified by code 52.805.80, is a replacement part designed for fuel connection management in the nautical field. It is a component tank side, designed to integrate neatly into the fuel line, with a practical configuration for maintenance and replacement interventions.

This version is equipped with hose holder, a typical solution for connection to fuel pipes by clamping with a hose clamp (not included, unless otherwise specified). The product is supplied by Osculati S.r.l. and is commonly sought as a replacement for systems with Mercury standards.

What does “quick connect” mean”

With “quick connect” refers to a configuration designed to be installed on the line/pipe, not as a fixed panel mount. This setup is useful when a functional and accessible connection along the fuel line is desired, for example near the tank or in a technical compartment, maintaining the possibility to intervene quickly in case of replacement or inspection.

Hose holder: simple connection to the pipe

The presence of hose holder allows the fuel pipe to be connected to the fitting, secured with a suitable clamp (not included). It is a common solution in the nautical field because it allows practical installation and relatively quick replacement of the line when necessary.

Typical applications in the nautical field

This coupling is indicated as a replacement or line component for fuel systems associated with configurations Mercury, especially when a male coupling tank side with hose holder.

• Routine maintenance of the fuel line, when an existing coupling is worn or needs replacement.
• Restoration of a fuel connection on systems already prepared with this standard.
• Fittings and refitting where consistency with components already on board is desired.
• Tank compartment interventions or near the fuel line, where a tank side component with hose holder is useful.

Note: Exact compatibility depends on the system configuration and existing fittings. In case of doubt, it is good practice to compare the shape and type of the existing fitting (male/female and tank/engine side) before purchase.

Advantages for installers and boaters

Targeted and easily identifiable spare part

The reference to Osculati code 52.805.80 helps manage order precisely, especially when working on scheduled maintenance or quick seasonal replacements. Having a clear code reduces the risk of confusing similar versions (e.g., male vs female or tank side vs engine side).

Practical solution for the fuel line

The configuration with hose holder is a common choice when a direct connection to the pipe is desired. On board, where accessibility and intervention times matter, this setup can be convenient to restore or update an existing line without unnecessary complications.

Consistency with Mercury components

When the system is set to Mercury standards, using a dedicated fitting allows maintaining uniformity in the fuel line and reducing uncertainties during replacement. This is particularly useful on boats where connections and pipes are already prepared for this configuration.

Use, installation, and operational notes

Checks before purchase

To correctly choose the fitting, it is recommended to check:

• That the requested component is actually configuration (visual comparison with the existing fitting).
• That the installation is planned tank side.
• That the line uses a connection to hose holder (tube that fits onto the fitting and is secured with a clamp).
• That the system is set to standard Mercury for this type of fitting.

General installation instructions

Installing components on the fuel line requires attention and good workshop practices. In general:

• Operate with the system in safe conditions and with adequate ventilation of the compartment.
• Check the condition of the tubing before inserting the hose holder (intact tube, not hardened or damaged).
• Use suitable clamping systems for fuel applications (e.g., appropriate clamps), without forcing more than necessary.
• After installation, perform a visual check of the connection and the surrounding area.

If you have no experience with onboard fuel systems, it is advisable to entrust the intervention to qualified personnel.

Maintenance and replacement

Fuel fittings are components subject to wear over time, especially in marine environments. In case of maintenance, it is useful to periodically inspect the line and consider replacement when signs of deterioration, difficulty in fitting, or suboptimal connection conditions are noticed. Keeping the line in order contributes to more reliable system management.

Summary

• Product: Mercury fuel fitting male quick connect
• Code: 52.805.80 (Osculati)
• Type: male, tank side, with hose holder
• Category: outboard spare parts and engines / fuel systems

For technical requests or to verify compatibility with your system, it is useful to have photos of the existing fitting and the product code reference at hand.
