Do I need an aftermarket fuel pressure regulator?

Truth be told, aftermarket FPRs are not necessary and the factory OEM FPR will do the job just fine. Even installing a Walbro 255L/H fuel pump and/ or larger injectors does not require you to switch to an aftermarket FPR as the factory one will cope happily.

Is there a difference in fuel pressure regulators?

The difference is that an aftermarket, adjustable regulator has the ability to adjust when that diaphragm opens using preload on the system. The size of your fuel lines also is relevant to pressure, Mills explained. The smaller the fuel line, the more pressure drop you’ll have over a given length of line.
