OFCOURSE!!!
I now can understand why none of my gauges work (only speedo works a little and amp gauge works) My chevy has been 12volt converted for a long time ago before before we shipped it to europe. I guess the old gauges are 6volt, and thus burned to death by the 12volt system? I dont know if these new geuges are 12 volt or not.
Anyway, the fuelsender, does it work with 12volt? or do i have to buy a new 12volt sender?
