| K500A To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} Copy to E.{Mr Elliott - Chief Engineer} re 25/30. Sg{Arthur F. Sidgreaves - MD}16/E30.6.36 I am rather concerned about the petrol pump failure on 22-G-V in France, with an air temperature of only 20.9°C and an under-bonnet temperature of 60. I assume this car had the standard flaps to the shutters and that they would have been open? If petrol pumps are going to fail to deliver under the conditions set out in this report, I am afraid we are going to have serious trouble with 25/30's in the hands of customers. Whilst I understand that E.{Mr Elliott - Chief Engineer} has under consideration the question of moving the petrol pump elsewhere, I was wondering whether the position would not be improved if we made up a screen lined with asbestos or something of that description to protect the petrol pump from the heat. For instance when I had my trouble last week, we found that one of the petrol pumps was not abnormally hot to the hand but the other was unbearably hot - showing that it is not only the air temperature that matters - (otherwise they would both have been the same temperature) - but their proximity to other parts. Could not the people with 22-G-V be told to put up a protecting shield and test the result? Sg.{Arthur F. Sidgreaves - MD} | ||
