Conways in line Anti-Sumping Valve is designed to fit unobtrusively in the Flexible Oil Feed Pipe A65.

It is automatically opened by the action of the Oil Pump's suction, and is a safe way of preventing drain down into the Crankcase when the Engine is idle.

Easily fitted and very reliable, it is suitable for Series "A's" and all Post-War Vincents with Single Start Oil Pumps.

Modestly priced, it is supplied with fitting instructions and Pipe Ferrules.

Here we have a photo of the valve on a Series 'C' Comet, fitted neatly behind the gearbox.
