Talking of old Rovers
I used to rather worry about the Lucas electric fuel pump feeding our RR-Continental 0200, which is EXACTLY the same pump as the one in my 1955 Land-Rover.
This complex 1940's assembly of elderly rubber diaphragms, springs, contacts, coils, magnets and points (points for gawds sake) is heroically unreliable in the Series One (and the Jags it was also fitted to) at the best of times - so I fitted a hidden electronic module to do away with the points. Not an approved mod for the Condor.
When flying I'm only reassured by the knowledge that the Condor has an additional mech fuel pump, and I secretly suspect that it doesn't actually need either pump, since the tank is nearly all above the level of the carb inlet !
