Condition of the cap is more important than pressure rating, but I'd
certainly go 7 lbs. The late MGB's have a black metal overflow bottle that
looks much more appropriate that the stuff you find at the general parts
stores... also the 68-69 MGC used a similar bottle. It sure looks better
than red plastic
If the radiator and bottle both keep emptying out you either have a fluid
leak in the cooling system or a duff head gasket... cross your fingers
