Lift pump next to the tank feeding a high pressure pump in the engine bay to feed the fuel rail. This is assuming it's a 14CUX injected engine, you only need the lift pump if it's on carbs.

I used Facet pumps from memory, with an indivudual relay and fuse for each, switched by the ECU.

EDIT: apparently the pumps are very sensitive to dirt, so I used a small filter before the lift pump and a massive one between lift and high pressure pumps.
