HATTON GARDEN, LONDON, E.C.1 5th May, 1930. Monday. Gentlemen, You may remember that we wrote to you some months ago, giving you particulars of the Petrolift Fuel Pump, for Automobile use. At the time of writing to you, we had perfected this Pump so far as durability and performance are concerned, and had received an official report from the National Physical Laboratory, who tested the durability of the Pump without any attention whatever over a period equivalent to approximately 150,000 miles' running, on a Car of medium horse-power. In the form in which the Pump was made at that time, however, it was rather too expensive to appeal to the Motor Manufacturer as an item of standard equipment. Since that time, we have been engaged in experimental work, with a view to cheapening the design, and we are pleased to be able to tell you that we have now produced a pump which has all the characteristics of reliability of our original model, and which we shall be able to offer to the Trade at a price which will compete favourably with any system of fuel feed on the Market. We would, at this stage, emphasize one important feature of our Pump, namely, that it delivers fuel at atmospheric pressure. We have consulted all the Carburettor Manufacturers of importance in Great Britain, and find them uniformly opposed to delivery of fuel to the carburettor under pressure, particularly in the case where this pressure is fluctuating, and we have ourselves verified, by tests on other fuel pumps, that there is an appreciable increase in the fuel consumption, together with | ||
