Check your feeds to the sender & the gauge, both live & earth. Also have you checked that there is actually petrol in the tank. We wouldn't want you to have to put new plugs in, take them out, put the old plugs back in, take them out, rebuild your carbs, twice, or anything like that just because you forgot to put petrol in the tank.

If it's not the electrical connections, it could be the unit itself. I took mine out of my tank recently and dis-assembled it. Basically a float moves up and down 2 very thin wires. My float moved very erratically and got stuck in one position several times.
I stuck the tube in a pint mug filled with diluted POR 15 Marine Clean. This is excellent at getting rid of sticky residue. The liquid promptly turned dark brown. After inverting it and leaving it for a while then putting it back together, I was amazed at the difference. Very smooth movement.
It might sound like hassle, but in my opinion, it will only improve the sender.

Having similar problem with my sender - definately works as when taken out of the tank and moved around with ignition on (watch for sparks lads) the gauge moves accordingly. Which is great. But a soon as it goes back in the tank then it just sticks againat whatever amount of fuel happened to be in the tank at the time.
Reckon a good old clean would do the trick but what do I use to clean it without contaminating the fuel? What's POR 15 Marine Clean and where can I buy a pint of it? Robster - what did you use? Would SPAR vodka work?
cheers,

After two years of having a non functioning gauge, swapped it for a spare 914 one and hey presto everything works! Felt a bit of a prat for not checking if they were the same before!
Have plenty of 914 senders in the shed if anyone needs one

Weird! It could be that your sender is touching the bottom of the tank - but that doesn't sound very plausible.
I do know that the new cork gasket I used was about 4 times thicker than the one I replaced.
I still have the odd problem with fuel level readings but I know that is down to the connecter being a bit loose.
