List, Thanks John & Dave for the EFI advise, I was well aware of the
problems of 'dead heading' the fuel pump and thought if a mechanical fuel
shut-off was still required the best option would be between the tank and
pump ie on the inlet side.
As a result of this discussion and subsequent explanation of correct EFI
workings, hopefully electrical fuel shut-off will be accepted in EFI cars
if Dave's tech testing proceedure is followed.
Is this List is becoming invaluable or what ?
