SU Type 90-Degree Double-Threaded Banjo in Brass
The SU type 90-degree double-threaded banjo in brass is a finely crafted fitting designed to improve both the functionality and flexibility of SU carburettor fuel systems. Made from high-quality brass, it offers strength, excellent corrosion resistance, and a secure, leak-free connection. With its dual-threaded layout and compact 90-degree form, it provides efficient fuel routing while combining practicality with period-correct style.

Durable Brass Construction

Produced from premium brass, this fitting is built to withstand the harsh conditions of fuel system operation. Brass is naturally resistant to corrosion, wear, and the degrading effects of petrol, diesel, and ethanol-blended fuels. Its robust construction ensures reliable performance under pressure and varying temperatures, while also providing long-term resistance to moisture and residue build-up. For owners of vintage vehicles, brass fittings also carry the authentic look and feel of original components.

Dual-Threaded for Versatility

The double-threaded arrangement gives this banjo enhanced adaptability within fuel system layouts. With two threaded ports, it enables multiple fuel lines or components to be joined at a single point. This makes it especially useful for:

• Twin or multi-carburettor setups requiring parallel feeds.
• Integration with accessories such as filters or pressure regulators.

This design streamlines fuel line routing, minimises the need for extra fittings, and helps create a clean, efficient system.

90-Degree Layout for Space Efficiency

The 90-degree angle of the banjo is ideal for routing hoses in confined spaces. Its shape helps to:

• Prevent hose kinks or sharp bends.
• Maximise available space in crowded engine bays.
• Maintain smooth, unrestricted fuel delivery to the carburettors.

Alongside its practical benefits, the right-angle design contributes to a tidy, professional-looking engine bay.

Designed for SU Carburettor Systems

This fitting has been engineered with SU carburettors in mind—found in many classic British vehicles. These carburettors depend on precise fuel delivery, and the banjo fitting ensures reliable flow and leak-free operation. Vehicles commonly using SU systems include:

• MG: MGA, MGB, MGC, T-Series.
• Triumph: TR Series, Spitfire, Stag.
• Austin-Healey: Sprite, 100, 3000.
• Jaguar: XK Series, Mk2, E-Type.

It provides both authentic functionality and a period-correct finish, making it indispensable for restorations.

Resistant to Modern Fuels

As ethanol-blended fuels like E10 become standard, material resilience is critical. Brass offers excellent protection against ethanol corrosion, ensuring this fitting remains serviceable in modern conditions while retaining its suitability for classic systems.

Straightforward Installation & Servicing

The precision-machined threads allow for quick, secure installation. The fitting is equally easy to remove and refit for servicing or tuning, without compromising reliability. Its sturdy construction ensures repeated use without damage.

Practical and Aesthetic Value

Alongside its mechanical performance, the polished brass finish provides an attractive vintage look that complements classic engine bays while still delivering modern reliability.
