| 1263 Rm{William Robotham - Chief Engineer}/J.B.Dixon (Chateauroux). Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}3/R.4.5.37. One of the Daily Reports on 35-EX mentioned that vapour lock has caused complete petrol failure of all three pumps, whereas another report mentioned that although the double pump had failed, the single one continued to operate. We have your memo this morning concerning the faulty manufacture of the double pump saying that since correction you have had no further trouble. Please, however, make sure before you return whether or not it is possible for the car to starve or come to a standstill due to vapour lock trouble when all three pumps are operating.
