so i want to remove the fuel tank and put a alloy fuel tank in the boot, but knowing knothing of this, are there tanks for efi and non efi (i want su's)
and what about such things as the fuel sender and m.o.t laws.

No real laws as such, but obviously if doing such a conversion it needs to be done right, with a proper fuel cell, and very securely mounted.
TBH, If I was doing it again, I'd buy one of the plastic style fuel cells available. I had my alloy tank custom made, and it was bloody expensive. It was a good job, but they did not make it exactly how I wanted it. Its 75 litres volume, but given how they made it with an internal collector, instead of a collector/sump. I can rarely let it run below 15-20 litres, as I dont want to risk pump damage.
There are various senders available. My Granada gauge was about 10ohms empty, and 65ohms full. Oddly, the tube style sender in mine works perfectly out of the tank, but once in tank, only works as far as a little over 1/2 full. Above that it still sits at half....no big deal though. It works enough for me to know when to fill up.
No idea why it doesnt work properly in-tank....very odd.
Efi and carb are very different. But a proper fuel cell will have good internal baffling, a fuel collector, and you could even get it with an in-tank pump, which can save hassle.
Efi systems must always have a good supply of fuel available for the pump, whereas carb setups arent quite as fussy, as they have a little reserve in the carb itself.
So the odd draw of air now and again isnt a big deal.
Its also a good idea to remove the rear seats, and form a metal bulkhead isolating the boot from the cabin ( refitting seats afterwards of course )
