I believe the reason Titen was asking that is to find out if the sender and gauqe are compatible. The float (sending unit) has a rheostat that varies the resistance as it goes up and down, if the ohm's aren't syncronized with the gauge it won't work or won't work properly. With some the guage show full with the highest reading and others it will show empty with the highest reading and if the current is wrong you will probably get nothing. So it's usually best to get a compatible sender with a new gauge whenever possible.
