The build date is Nov.93. Makes it sound older but build date is probably better than date of sale, 29.6.94.
The VIN is YV1945856R1106613
I will look for a tyre valve type T piece in the fuel line to the second (pressure) pump.
And I will check the fuel filter with that pump.
I am terrible slow with doing things but my youngest (and last) moves out of home on Sat 4 July (tomorrow, yahoo) so I hope I will be able to focus on the 940. There seems to be no cure for getting slower as you get older. Your various suggestions are invaluable and encouraging.
I will keep you posted with progress.
