Mr. EV{Ivan Evernden - coachwork} E.3/HF.{H. W. Frost - Coachwork Inspector}15.12.33. Bentley Chassis - Sealed Petrol Fillers. Referring to memos Cx.{Major Len W. Cox - Advertising Manager}16/KW.6.12.33 and Cx.{Major Len W. Cox - Advertising Manager}9/AW. 12.12.33, we have issued a design - RR. Sch. 533 produced in DY{F R Danby}'s department for sealing the Bentley petrol filler and providing a suitable vent, and this scheme is based on the one which has been recently tested by GVH on the 10,000 mile Bentley, and reported on as satisfactory. A suitable fitting and baffle has been added on the inside at the top of the filler body just below the cap for a flexible hose connection to a length of .250 diameter metal tubing, this tubing being fixed to the coachwork at the rear of the body and led out to a position just behind the number plate. We are attaching a blueprint of RR. Sch.533 to EV{Ivan Evernden - coachwork}'s copy of this note to enable him to make sure that it is suitable from the coachwork point of view, and to make preliminary arrangements regarding bodies in hand. The vent connection has been made to the inside of the filler with the special object of avoiding the surge of petrol which pushes up into the filler on the outside when taking a bend, but we do not think it would interfere with the luggage as it is an inconspicuous feature and has been well rounded off, and also the angle of the pipe connection is pointing downwards and towards the rear. We do not think it advisable to make any reduction in the height of the filler because, firstly, we think you will find this less convenient to reach when filling, secondly it would tend to reduce the rate of filling, and thirdly it would be a distinct disadvantage to the vent scheme in reducing the height at which the tank is vented. We propose to immediately equip all production Bentleys with RR. Sch.533, and we are seeking W.O.R's agreement to do this, because although the details of the construction are naturally different from the scheme which was rigged up experimentally, there is no change in principle. | ||
