I thought most all fuel injection systems ran at high fuel pressures
all the way from the tank (where the pumps are located) to the injector rails.
I know that injection systems are required to have a cutoff valve that
stops the fuel pump when the engine quits. Perhaps you could modify this switch
to shut off in the case of extremely high mass flow - like a broken fuel line.
You could measure the difference between the mass leaving the tank versus that
returning.
