Our Ref: TCS/HMH. 23rd August, 1933. W.A.Robotham, Esq., Messrs.Rolls Royce Ltd., DERBY. Dear Mr.Robotham, Thanks for your letter of the 22nd and the information re Continental pumps is very interesting. I should very much like to get hold of an Autoflux. In all probability they recommend this pump to be fitted as far away from the engine as possible, as the pump is not capable of coping with a vapour lock. Our pump, apart from the noise it makes, will cope with it. I feel inclined to think myself that fitting it on the chassis in the front will be satisfactory. This is especially the case as the pump having a more powerful suction stroke than delivery stroke on a hill the pressure on the delivery stroke will be reduced. Ithink it will probably be necessary for you to have the pump half way down the chassis and to fit a stronger spring to increase the pressure. I think it will also be necessary to have a fairly large air bottle on the delivery side. Under these conditions I do not see why the pump should not be satisfactory.
