I've just installed a set of rev counter dash clocks in my 95 M 1.3 LX and everything works fine except the fuel gauge is reading incorrectly. It seems to point where the old twice the size one would be pointing. The fuel gauge itself seems to be working as it's going down (as I'd expect!) but still seems to point to where the old one double the size would be pointing. It seems like it's getting the wrong signal from the fuel sender to be honest. Should this work correctly from the off or is the simple fix to swap in a fuel sender from an SR or a Super S?
