Carburettor Float for the SU carburettor float chamber, within the fuel metering circuit of the 3.5L V8 twin-carburettor petrol engine.

The float rides on the fuel standing in the float chamber and acts on the needle valve at the fuel inlet. As the chamber fills, the float lifts and closes the needle against its seat; as fuel is drawn off through the jet, the float drops and the valve reopens. The result is a constant fuel level held at the jet, which is what fixes the mixture strength the carburettor delivers across the engine's operating range.

A float that has become fuel-logged or distorted no longer closes the needle at the correct height, allowing the level to rise and producing flooding, fuel spillage from the overflow and persistently over-rich running. Float level should be checked and set to specification after fitting.

Frequently asked questions

What is the SU carburettor float used for?
The SU carburettor float controls the fuel level in the float chamber on the 3.5 V8 twin-carburettor petrol engine. It rides on the fuel and closes the needle valve as the chamber fills, holding a steady level for the jet. This is the left-hand carburettor float, supplied with gasket.
Which engines use this SU carburettor float?
This float fits the 3.5 litre V8 petrol engine with SU carburettors, as used on the Land Rover Defender, Discovery 1 and Range Rover Classic. It's the left-hand unit. Later fuel-injected V8s have no carburettor float chamber and don't use it.
Does the float come with a gasket?
Yes, this float is supplied with its gasket, so the float chamber joint can be resealed when the float is fitted. On the Range Rover Classic the float is also serviced as part of a carburettor kit. A fuel-logged or sunk float upsets the chamber level.
