Those wiring looms are fine, all you need is one M4 and one M5 nut to secure the ring terminals on the pump, and the loom runs from the battery and plugs into the relay and the pump. Good luck getting a new bracket though...... Just get the old one shot blasted and powder coated, it looks in good nick from the other pics you put up. If it's not going to be over stage 3 i wouldn't bother with a new pump or loom.
