Oil Pump Suction Pipe modified, and Fins arranged on Pump Chamber Cover to collect dirt. Cylinders. It was necessary to go over the Cylinder Tubes to stop leaks. Cylinder Head. The condition of Monel Metal Tubes was excellent, no signs of water leaks on test. There is no doubt that these Tubes stand up much better than Mild-Steel Tubes. RHC.{R. H.
