Ohh I forgot about this thread. So I contacted pretty much every supplier/retailer in Australia who listed Sumitomo terminals and no one had them.
Ended up ordering overseas from Corsa Technic and grabbing heaps of Tefzel cable, seals, heat shrink, connectors and other bits and bobs that are way cheaper over there than in Aus to make the near $60

postage more bearable.
This is the 18cent terminal required:
https://www.corsa-technic.com/item.php?item_id=349I wired up the relay as normal. Feed wired straight from the battery to relay and then to the pump connector, ecu power wire is repurposed as the relay trigger and earths wired appropriately. Engine start had more kick to it straight up and bonus is the relay has been mounted in a hidden position that I can easily reach should I want to remove it for extra theft prevention if parked up somewhere (though there’s probably a higher chance I’d lose the relay and be stuck somewhere than the car being stolen)
