5.0L Engine from a '93 donor. Stock fuel injectors are 19 lbs/hr @ 39 psi. I am considering an upgrade to Bosch F1TE injectors at 24 lbs/hr @ 43.5 psi. The stock fuel pump is 110lph.
Question : Do I need to upgrade the stock fuel pump to achieve the higher psi required of the Bosch injectors? Or can I achieve the same result with an adjustable fuel regulator with stock fuel pump? Safer to upgrade all 3?
Goal - increase HP by increasing injector flow rate.

My guess : upgrade all 3, pump, regulator & injectors.
