Thanks for the heads-up, Harry - that's a really good point (even though it 
doesn't get really cold here, because of Global Warming) (;-)).

The expansion of fluids and gases is easy to overlook. I once filled my Ford 
Anglia *right to* the brim with fuel on a really hot, sunny day, then drove 
it 200 yards and left it parked in full sun all day. When I got back to it 
there was a large pool of overflowed fuel underneath it - the expansion on 
leaving the cold storage tank underground, and then sitting in full sun at 
80+ degrees, was considerable.

Cheers

Alan
