| C O P Y OUR LETTER SENT TO : Major Gen. C.E.E. Curtoys, Grey Wethers, Tavistock, DEVON. 3rd September 1936. Dear Sir, We are in receipt of your letter dated 3rd inst., and very much regret to hear of the trouble you have experienced. This may be caused either by a fault in the pump or in the installation. The usual cause of noise is an air leak on the suction side of the pump, and the simplest way to check up for this is to disconnect the flexible pipe from the carburetter and allow the pump to pump petrol into a can. If the end of the pipe is then submerged in the liquid you will be able to see if any bubbles come through. In order to make sure whether the pump is to blame or not, we are sending you a further pump under separate cover, and shall be much obliged if you will kindly return the one at present fitted to us marked " For the attention of Mr. Kent" As regards the sudden failing on a hill, probably the simplest way of getting down to this would be to wait until this occurs, and then to switch off and go into neutral. If you then remove the cover of one of the float chambers, you will be able to see whether this drying up is due to lack of petrol or some other cause, as if lack of petrol is the cause, the float chamber will be empty. There are, of course, various other things on a car which can cause these symptoms. Yours faithfully, FOR THE S.U. COMPANY. | ||
