Got the mini out today fuel gauge didn't move, put 5l in still the same. Checked wiring and fuses, does the fuel gauge run through one of the relays on a 1991 carb, not sure if I misread the diagram?

Thanks

Earth the wire that connects to the tank sender. See if the gauge rises to full.

Does the temp gauge work?

Didn't have time to check continuity, had a quick look at the insulation on the G/B wire and checked the fuses. All other electronics working

As suggested by jime17, disconnect the two wires from the sender unit and connect them together. If the gauge then rises to full, it proves there is a problem with the sender unit.

Also if it is the sender is it easy to replace? I'm guessing I would need to drain the tank?

Easy to replace the sender.

The fuel level only needs to be below the level of the sender backplate.

Stick a garden cane down the filler neck to gauge how much fuel you have.

Probably best to disconnect the battery.

Remove sender wire(s).

Take a hammer and punch. Knock the locking ring Anti clockwise about a 3rd of a turn.

A twist and wiggle will have the old sender out.

Installing the new one can be a bit of a fiddle.

Replace the gasket!

Keep the float as close to the side of the tank as possible, or it will catch on a baffle. You may have to insert it at completely the wrong angle, then rotate it at the last moment.

Then knock the locking ring round clockwise.

Okay thanks for the advice! Fuel gauge is faulty will get on order to replace next weekend. Says it's comes with the gasket and clip so will change anyway

Hi guys, just put the car back and fuel gauge is now working :S. Is it common to be an intermittent fault? If not it may be a bad connection on the connectors

Did you connect the wires on the sender together?

Sorry should have said fuel sender. Connected the wires and gauge went to full. Put spare connectors back on tank and left the car for a few hours. Came back and the gauge now reads correct

Personally I'd purchase a new one and keep it stored so if the fault returns you can swap it without losing too much time
