Please receive herewith E.CD.67 Connection for Oil Pressure Gauge. The connection originally was situated on the pressure filter cover, but as this unit has been deleted and the main pressure oil is now on the near side of the engine, we have supplied a boss on the pressure oil inlet to crankcase; this boss should be added to crankcase as soon as possible, so that it will appear on the modified crankcase now being prepared. A new pipe to pressure gauge is required. DA.{Bernard Day - Chassis Design} | ||
