I was driving my friends 101 Giulietta Spider Veloce today and noticed that it had a 0-80lbs oil pressure gauge. My 750 Spider Veloce is 0-110lbs. I have checked my stock and some are 80s and some are 110s. My SZ (750 engine) is an 80 too. As a matter of interest both my 750 cars run 60lbs at 3000 or so.
The only difference in the gauges listed in the arts book is English or Italian lettering

The "110" gauges are measuring oil pressure in pounds per square inch, whereas the "80" gauges are measuring oil pressure in kg per square centimeter times ten. My US-spec Giulietta Spider has a "110" gauge, while my Euro-spec Sprint and Berlina have "80" gauges.
