Jay &19Fordu are right. However guys, If you use a 73 -10ohm sender you CAN get a reasonably accurate reading. You might have to adjust the float position a little though.
After mucking about with my original bimetal KS sender unit I finally bit the bullet and bought a 73-10 ohm unit just to see how accurate it would be. I wasn't expecting it to be as accurate as it is ! Pleasantly surprised actually. It's been in my 52 Customline for about a year or so now.
