We have had a number of requests from customers to fit a Drain Sump and Plug to Phantom Autovacs and we fit the Sump F.74297. We suggest that this Sump and plug should be fitted as standard on all autovacs as is already stendardised for the 20 HP. We consider that it is a most useful and ready way of clearing away water etc., which so often is found to have accumulated in the Autovac Tank. Hm{Capt. W. Hallam - Head Repairs}/NRC.{N. R.
