SU Float Needle Valve regulates the fuel level in the carburettor float chamber on the 3.5L V8 petrol fitted with SU twin carburettors.

The needle is controlled by the float: as fuel is drawn off the float drops and the needle lifts from its seat to admit fuel from the pump, then reseats as the level rises, holding the chamber at the set height. A worn needle or seat leads to flooding or fuel starvation.

Frequently asked questions

What does the SU float needle valve (STC205) do?
The STC205 float needle valve regulates fuel level in the carburettor float chamber on the 3.5L V8 petrol with SU twin carburettors. The float controls the needle, which lifts off its seat to admit fuel and reseats as the level rises, holding the chamber at a set height.
What are the symptoms of a worn float needle valve?
A worn needle or seat typically causes flooding or fuel starvation, because it can no longer seal or meter fuel correctly. Fitting a new needle valve restores a stable float-chamber level and consistent fuelling.
Which models use this SU needle valve?
It fits SU twin-carburettor 3.5L V8 applications on the Defender (1987-2006), Discovery 1 (1989-1998) and Range Rover Classic (1970-1994). Confirm your engine runs the SU twin-carburettor setup before ordering.
