Anyway, moving swiftly on...
Seiing as it's quite hot today, a balmy 35°C in the shade, I thought I would do a run out in the Austin for Bob's benefit, seeing as he's been having some problems recently with vapour lock. I took the car out and drove it to the summit of Mont Bouquet, a round trip of 35 miles. Bob knows the climb because he did it in his RN when he came over here for an old car do in 2008. It's not very high (relatively, it's about 650m), but it's bloody steep. The road to the summit from Brouzet les Alès is a 5km slog with gradients of 6% then 12% and a final run to the top of 10%. It's not for the faint of heart although to someone in a modern it's just a pimple. For Austineers and cyclists it's the gateway to hell.
I managed to get to the top today without incident, to great applause from a bunch of parachutists at the summit. The RP never missed a beat. Bonnet closed, windscreen and vents open. I was a trifle warm but the car was never fazed. The descent is as hairy as going up, which required a few notches on the handbrake and 3rd gear to ensure that gravity and momentum didn't take over.
My conclusion Bob, is that there is probably something relative to your particular car that's causing the vapour locking. Since I fitted the 4 blade fine mine has been absolutely fine. Changing the loop on the fuel feed may well help.
Couple of pics and a video link attached.

Apologies for the crunchy changes but I was doing all this one handed (noone was looking)
