BENTLEY AND PEREGRINE PETROL TANKS. This is to confirm our conversation that you will look into the question of baffling the reserve pipe in the tank. At presnt the petrol surge, when cornering etc. frequently uncovers this pipe when there is as much as 5 or 6 galls. in the tank, and this causes the petrol pumps to suck air. In the case of electric petrol pumps sucking air causes noise, whereas with mechanical pumps it is likely to cause temporary starvation. The reserve could with advantage be run in a depression in the tank, otherwise it is difficult to pick up the last 2 galls. It will be appreciated that we have never run into this difficulty before because we have always used autovacs which can prime a dry pipe line without difficulty. We should like to bring in the improved baffling on the 18 galls. tank, and get it on our first Bentley car. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
