Have you lifted the rear passenger seat? I found a hole just above the fuel sender unit on my Ruby Mk 1, very easy access to the fuel sender.

Thanks for the info Nigel.

Although this thread is primarily concerned with the mechanics of physically removing the tank, a number of relevant electrical issues have crept in!. I suspect by now you have succeeded in removing the petrol tank, by attacking the 'U' bolt fixings. When you come to putting it back, its a good idea to run a separate earth wire between the sender unit to the earth connection on the back of the petrol gauge. It's very often not the gauge or the sender at fault, but the appallingly bad earth return path that relies on the bodywork/chassis to act as a conductor. The 'genius' who came up with that money saving concept should have been pubicly flogged years ago!
Remember the petrol gauge is not a simple rheostat (as we were probably taught at school) - there is another coil involved.
Good luck with the tank removal etc. you'll find it more dirty than difficult.

Thanks for the info Bob. Haven't got round to battling again with the Ruby fuel tank. The family are keeping me out of the garage at the moment, I would live in there if I was allowed.
Cheers,
Darren

To be honest Jeff I haven't tried them yet. I'll purchase a set and try them before getting the Dremel out. Thanks for the advice.
