I have two pumps in parallel on the BN1. To minimize leakage and to
simplify the connections, the main pump (an SU) is linked to the spare via
double banjo connectors. John Trifari BN1/BJ8 Golden Gate AHC

Keith,
I do understand why you want to put them in series but if you
accidentally switch them on both you have double the fuel pressure.
Better fit them parallel with an electrically operated valve (4) before
and after each switch. The valves are operated by the same feed wire as
the corresponding pump. These valves are easily sourced from LPG fitters.
This way there is no circulation through the faulty pump and you will
have no leakage if something horrible has happened to a pump.
