Could you then run an alarm on fuel pressure or delivery? Mark Shead said he can cut the engine on low oil pressure, surely the same can be done on fuel or running lean?
Surely though if one pump drops to min fuel pressure then the same happens with two, after all it is about pressure and supply. Could one pump not supply 100% even if one fails?
