Radium Engineering

Does your fuel system need to keep up as the engine makes more power? Radium Engineering makes fuel and fluid system components built for performance cars, track cars and high horsepower projects. Here you’ll find surge tanks, pump hangers, fuel rails, fittings, oil catch cans and expansion tanks for many popular cars.

American fluid system specialist

Radium Engineering is an American company specialising in everything that moves fluids around a performance car: fuel, oil and coolant. The parts are typically machined from aluminium and designed to solve specific problems that appear when an engine is built up. That can be fuel starvation in hard corners, a lack of pump capacity or oil vapour in the intake. Many products are made as direct fit replacements for specific models, while others are universal building blocks for custom projects.

Radium Engineering’s key products

Fuel surge tanks and pump hangers are among the most popular products. They ensure a stable fuel supply and make room for one or more stronger pumps. Fuel rails and fittings make it easier to build a complete system for larger injectors and E85. Oil catch cans collect oil and vapour from the crankcase ventilation so less ends up in the intake. The range also includes coolant and power steering expansion tanks as well as filters and pressure regulators. See each product for fitment and connections.

Frequently asked questions

What is a fuel surge tank?

A surge tank is a small extra tank with its own pump that keeps a constant fuel level at the engine’s pump. It prevents fuel starvation when fuel sloshes around in the tank during hard cornering, acceleration or braking.

Why fit an oil catch can?

A catch can collects oil and moisture from the crankcase ventilation before they reach the intake. This reduces deposits on the valves and in the intercooler and is especially relevant on direct injected and turbocharged engines.
