If this is a 67B as your signature suggests then -
1. The water temperature gauge should be the combination oil pressure/water
temperature gauge. It would work regardless of the ignition being on or off
as its a bit more primitive (mechanical rather than electrical). Its
possible the needle is stuck. I had one that would barely respond. Either
way, you can have it serviced at Nisonger or Mo-Ma (Momanm@aol.com). You
have to remove the gauge plus the long cable that leads to the temp sensor
in the block (its all one unit). The oil pressure part, a small oil line,
disconnects at the gauge. Costs about $90 or $95 for complete repair and
calibration.
2. I agree on the fuel cap. Its hard to believe a MGB fuel cap could seal
so good to allow pressure build up although I did see this with my son's
65B. Back in 67 there wasn't as much concern about trapping fuel vapor -
that came later (1970?) with the fuel vapor separator and the charcoal
cannister. The label on your cap sounds like it is the wrong cap to me.
