Good evening all

Can anyone help with a dumb question please ?

My fuel gauge doesn't appear to indicate correctly and I am wondering if I have missed something with the wiring at the sender.

There's just one wire to the sender which I imagine must rely on the sender body being earthed to make it work ? If so is it better to earth the body of the sender, or earth it via the tank body ? Is it good practice to earth the tank itself anyway ?

Any help gratefully received please !!

Thanks
Simon

i'd take the belt and brace approach and earth both.

the circuit should be:

12 V ---- gauge ------- sender ---- earth

Just test with an extra wire. Say from the battery to the gauge, or the tank. Easy to do and you'll have the answer straigt away.

Thanks all, earthed the sender body and the tank and all works perfectly
