I recently refurbished the entire fuel system on my P5, because the car had been sitting for 25 years, and in the process replaced the fuel-level sending unit. It now doesn't work, i.e. I get no reading at the gauge.
I have this additional information:
The fuse is fne.
The gauge reads full (although the tank isn't) if I reverse the wires.
When I check the live wire at the sender with a test light, the light pulses and is relatively dim.

I recently removed my sender to clean out the tank of rust and silt. I noticed the 'gubbins' on the sender was actually quite rusty. It moved ok when I took it out but had stiffened a day later when it went back in. The tank has read 1/4 full ever since so I can only guess the sender arm has corroded inside the 'gubbins' and stuck!
I've been trying to find a new one without luck so pretty soon I'm going to have to take it out again and try and free it up I suppose. Could be the same with yours?

Thanks for the responses. Roy's description matches my car before I replaced the sender, but the new sender seems to not work. My sense (and that's all it is) is that it's an electrical problem, so I'll study John's link and see if I can make any sense of it.
