| X3701 Oy4 - C 28921 Sept. 28, 1921 Mr. Claude Johnson, Managing Director, Rolls-Royce Ltd., London, England. Attention: Messrs. F.H. Royce & Hives. Dear Sir:- X3701 Re: Freezing Up Of Petrol Filter Replying to R4/G7/9/21 - We think that the stoppage which Mr. Hives experienced continually in the small carburetter on 4-EX was due to water, unfrozen, accumulating on the fine Monel Metal gauze. Therefore, we fear that a small filter on the carburetter such as Mr. Hives had on 4-EX, would not be suitable for American conditions. The filter on the gas tank is washed by the movement of the car and is therefore less liable to get blocked by water, but we do imagine it is quite liable to get blocked by ice in extremely cold weather, although we have not heard of this occurring. A great deal of water is found in American gasoline, though why this should be so we do not know. The average vacuum tank when drained, on an ordinary car after running a few months, will deliver three or four teaspoonfuls of rusty water. This, we think, is universally experienced in the States. American Gasoline, on the other hand is, generally speaking, free from the dirt, fragments of paint, road dust, etc. which are introduced into the tank through the use of separate cans, as in Europe.
