Also as I understand it the 1s system operates by wire number 2 (grey) from the pump being grounded by the boost switch under no boost (pump off) and when boost is sensed over the preset level the wire goes open circuit and the pump works, is this correct?

Two 0.4mm jets will only give half the flow of a 0.8mm jet. You would need to run four 0.4mm jets for the same flow/pressure drop. I suggest running one 0.4mm jet per intake runner
