Carter black fits the bill. 397 lph free flow which is more or less what it's doing from my main tank to my surge tank and back. The 044 is only about 300 at low pressure, through to 200lph at high pressure.
Does this car have an 044? I thought not? A smaller/cheaper/quieter carter would do the trick, if not, and possibly even if so.
For 300 or 400hp you could PWM an 044 and get the peak flow way down, noise down, fuel heating down, and power consumption down. The only reason to run more than you need is FPR linearity which generally only needs 50-100hp worth of fuel in excess to be similar to the idle value. I have an ozzy regulator on my desk that's tested to be more linear than most, but requires an extra 200hp of fuel flowing through it to not fall into the non-linear region. In any case, 044 is good for quite some hp at full voltage.
Re injectors, you can go lower than that figure for two reasons: 1) less than full-on duty cycle and 2) the surge tank's job is to buffer your needs, hence comments about salt flats vs street driving, though I guess if you like to burn down the freeway at double or triple the legal limit, you'd need the lift pump to supply full flow. You also want the lift pump to be refreshing the heated fuel in the surge tank with cool tank fuel as much as feasible without further heating by the lift pump itself.
