🔌 Function

The float chamber body stores a controlled volume of fuel, allows vapour separation and supports the float and needle-valve system that maintains the correct fuel level for the high-pressure injection circuit.

⚠️ Common Signs of Failure

• Fuel leakage from cracks, corrosion or damaged sealing surfaces
• Engine starves for fuel at higher RPM
• Flooding caused by a sticking float or worn needle valve
• Contamination or varnish inside the chamber restricts fuel flow
• High-pressure pump cavitation caused by an unstable VST fuel level
