Just a thought, but are we all doing our backup fuel pumps incorrectly????
Someone mentioned to me the other day, what if, the main pump fails in
such a
way as to totally block the system. Would the backup pump be able to push
the fuel
past the blockage? I guess probably not. Should we not be paralleling the
main pump, with
a non return valve after each pump, so pressure is not lost back through
the other pump.
I realise the convention is to series the pumps, to "lift" the fuel to the
main pump, but
is the convention correct, or is this giving us all a false sense of
security.
Just a thought.
