SU Type Square-Based Pump Banjo (3/8 Pipe) in Brass
The SU type square-based pump banjo (3/8 pipe) in brass is a precision-engineered fitting designed to provide a secure and efficient connection for fuel lines in vehicles equipped with SU fuel pumps. Manufactured from high-grade brass, it offers long-lasting durability, excellent corrosion resistance, and full compatibility with both traditional fuels and modern ethanol blends.

Its robust construction not only guarantees a stable and leak-free joint but also complements the authenticity and period-correct aesthetics of classic British vehicles, making it an ideal choice for both restorations and ongoing maintenance.

Strong Brass Construction for Long Service Life

This banjo fitting is machined from premium brass, a material valued for its strength and natural resistance to corrosion. It is particularly suited to automotive fuel systems, where components are exposed to petrol, diesel, and ethanol-based fuels over extended periods.

Brass construction ensures the fitting retains its structural integrity under pressure, fluctuating temperatures, and harsh operating environments. This makes it a reliable solution for enthusiasts of vintage vehicles as well as for those maintaining modern systems.

Key qualities include:

• Leak Prevention: Secure seating minimises the risk of fuel leakage, protecting efficiency and safety.
• Even Torque Distribution: The square base spreads tightening forces evenly, reducing the chance of distortion.
• Secure Positioning: Remains firmly seated under vibration or engine movement, ensuring steady fuel flow.

These features make it especially suited to vehicles running mechanical SU pumps, where consistent delivery is essential.

Made for 3/8-Inch Fuel Pipes

This fitting has been specifically designed to integrate seamlessly with 3/8-inch pipes, offering:

• Uninterrupted Flow: Smooth internal passages support efficient fuel delivery.
• Reduced Pipe Wear: Precision fit minimises strain and abrasion on the pipework.

Such compatibility makes it ideal for original-spec classic systems as well as custom fuel setups requiring robust, reliable connections.

Tailored to SU Fuel Pumps

Purpose-built for SU fuel pumps, the square-based banjo ensures a perfect fit with factory designs. It maintains both the functionality and authenticity of SU-equipped vehicles, including:

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

The fitting matches original specifications, making it an essential component for restorers seeking period-correct accuracy.

Resistant to Modern Fuels

With ethanol-based fuels like E10 becoming more common, material resilience is vital. Brass resists ethanol-induced corrosion, ensuring this fitting remains reliable across modern and classic fuel systems alike.

Efficient Right-Angle Routing

Its 90-degree configuration allows neat and practical hose management:

• Tight Bays: Ideal for compact or crowded engine compartments.
• Organised Layouts: Avoids awkward bends and kinks in fuel hoses.
• Consistent Delivery: Maintains smooth, uninterrupted fuel flow.

Easy to Install and Maintain

Designed for straightforward use, the banjo is quick to install and equally simple to service. It withstands repeated tightening and removal without compromising integrity, while the robust brass body reduces maintenance requirements over time.

Vintage Aesthetic Appeal

The polished brass finish provides a touch of period charm, complementing the look of classic British vehicles. Its traditional style helps restorations remain authentic, while also presenting a refined finish under the bonnet.

Versatile Applications

While optimised for SU pumps, the fitting can also be applied in:

• Classic Car Restorations: Maintaining originality and functionality.
• Custom Fuel Systems: Reliable choice for bespoke builds.
• Industrial Use: Dependable in machinery fuel delivery systems.
