The pump arrived and my Jazz is running again. At the end it took just under three months.
For last months I have been driving 25-35 years old cars, and it was actually very nice. If I could get Peugeot 309 as a new car and with full spare part support, I'd take it any day over any nowadays car. It has so good steering, very comfortable seats, great visibility, less electronics and no annoying systems to interfere driving.
