It's the 240-33 ohm range isntead of the 0-90. (33 might not be right, but it is inverterd)
I've had terrible luck trying to find an aftermarket sender for my cell that works right. The one I have now reads backwards and is terribly inaccurate with the stock fuel level tables. Tried switching the polarity and it stopped working altogether. I'm hoping I can get that straightened out when I do a custom fuel cell.
