Hobsons' were supplied with the Production Petrol Tank F.56260 for the above Chassis for calibration purposes, they found that it was not possible to record more than 13 1/2 Gallons on the Gauge owing to the height of Petrol in the Tank covering the pressure balance chamber. We herewith forward you Blue Print of:- F.56428 Saddle for K.S. Telegauge. to replace F.55648, on the above Tank to overcome this difficulty. The K.S. Gauge will of course require modifying to suit.
