| Da{Bernard Day - Chassis Design}/EVL/16.6.30 contd. We would be gladif you could tell us whether such a tank is satisfactory as it has a certain appeal - (a) it dispenses with the vent on the filler which is a nuisance from coachbuilders point of view, (b) when a muff is used on the hose of a petrol pump the vent is also bunged up, (c) it cannot be a very large dia. (2) If this tank is possible then we suggest that we might be able to try with advantage the original instrument board fitting having a long back leg of two diameters, and a tank at the top of the gauge glass, but without a balance pipe and without a pump. (3) The tank fitting which would have only two connections should be like that originally schemed, and sent to WW. and shewn on N.sch.2571. The Sprengle pump would be of the latest design as suggested in OY's memo, having a 40/1000 inley hole, and a 5/16th vent pipe which would be led into the main air vent.
