Ammy thank you for your reply!
Today reading the Beta Data book, I've seen this "NOTE" , speaking of oil pump
So, the maximum oil pressure must to be 4,5 to 6 bar;
an oil pressure sender with a scale of 0 to 8 bar, will transmit a lower pressure to the gauge on the dashboard..
Some friends of Fulvia forums discuss on it, because a dash gauge marked Jaeger or Veglia Borletti, need an oil pressure sender of the same brand, scaled at 0-6 or 0-7 bar
If not, the gauge on the dash, with an hot engine, still remain in the first half left of the instrument scale
The Lancia Thema 8V too, seems to be a oil sender of 0-6 bar..
