Fuel Pump and Fuel Pressure for stock 1UZ (boat application)

[converted]

Hey giuys, Ive done an extensive search on the forum regarding fuel pumps and pressure settings. I assume the Lexus car would have an in-tank EFI fuel pump...most cars do.
Anyway my 1UZ is for a boat.
Im running a stock 1UZ so I was wondering whats the cheapest and most reliable EFI external pump to get, Im thinking of a commodore or falcon V8 one and also whats the best pressure to regulate it at with stock injectors?
My thinking stock is around 40psi, but my stock SR20 race car with autronic/quads is optimised at 60psi!! with 330 injectors.
Oh forgot to mention I will be running a stock loom ECU setup to start with.
Your thoughts would be much appreciated.

Bosch 070 which is factory fitted to VL commodore will be fine for an external pump. I would stick with the factory regulator. Which loom /ECU setup are you using?. I did a factory management using the 26/22/16/34 loom MY1994 with the 4 wire oxygen sensors and had several issues and would not recommend doing it. The early looms with single wire oxygen sensors maybe alot better as they are not as clever. Cheers

I havent bought the engine yet but I will make sure its a 1uZ with a 2 wire O2 sensor system.
