MG Midget and Sprite Technical - 1500 expansion tank

I am having problems with the expansion tank on my 1500, the tube that goes to the bottom has rusted through at the top just in side the tank i have managed to get another tank which looks like going the same way soon ,i have put a plastic tube down the inside of the tube and sealed it round the outsides of the tube.not sure how long it will last but as tanks are no longer available,and i was wondering if i could use one of the tanks in the photo,my question is will the tube connecting at the bottom of the tank be ok, i cant see why not as it will be under the water level so should be just the same as it going in the top through a tube to the bottom.hope all this makes sense.

Yep, that'll work--

Moss are still showing the midget one as in stock but not cheap at 100 quid

Make sure the cap is the correct pressure, they might be interchangeable? 15 PSI I think... Then should be good to go.

my car is a 1500 and a different one.the moss one are for earlier cars.The cap the ally tank comes with is a 16psi one, i think that makes a 3 degree f difference in water temp or you can get a 13psi cap.
