Do you think it's a fair assumption that the pump would run on a typical cold damp British day ie low 50's?

On initial startup, yes. BUT if warmed up and not sitting for too long (where pressure may drop after a period of time), no. If you suspect a drop in pressure, then get the test done at the schrader port on the fuel rail. Otherwise, hunt and peck for a solution (used to be called and still is 'the shotgun' method), that usually costs a lot more in the long run. Good Luck!
