Stock pressure will be 8-10 at idle. And will probably drop to about 5 at WOT. As long as your above 2psi your fine. Bosch specs are -5 to +15, 650ml in 10 seconds is the stock flow rating, for an in the tank pump, but you could have one on the engine, either or for the 04's but im not sure if there is a different rating between the two
