R petrol tank specially arranged for draining any accumulation of water, or the petrol out of the main tank. The vacuum feed tank on the dash is of extra large capa-city which permits the car to run for a long time at slow speed without closing the throttle to obtain the necessary vacuum for refilling. This tank is fitted with a needle valve so that the petrol can be turned off for safety when necessary. (Y). TYRES. These chassis have been run at high speeds on rough roads in France for many tens of thousands of miles, and have prov-ed{J. L. Edwards} the great superiority in lasting qualities, convenience, and economy, of the straight sided cord tyres (easily detachable beads) and we strongly recommend intending purchasers to adopt these tyres which we have arranged to be our standard. So good and convenient are these tyres, that it is unnec-essarily wasteful to carry a second spare wheel. In addition to the single spare wheel, one or two spare tubes is all that is nec-essary for the longest of journeys. During our severe experience the absence of trouble has proved the justification of fitting the proportionately very large tyres adopted. ( 13 ) | ||
