you will need a pump that can do 65psi, a 255gph would be best.
keep in mind that if you plan on using the stock pcm untuned you will need to set your regulator to 58psi and leave the refference line unhooked. the stock fuel system runs a static 58psi with no modulation of fuel pressure. if you plan to tune, running the refference line is deffinitly a plus, itll allow you to go farther with the injectors than you can without the refference line hooked up.

Would a Walbro 255lph work for this application and a regulator with a return in it? Just want to make sure before I order parts can't afford to do it twice. All the fuel lines will have to be custom.
