Do I need a fuel pressure regulator?

OK, here's the deal, Im running Megasqiurt efi on my Z. When I bought my fuel system, the guy told me the fmu he sent in the box was to replace the fpr. Is this correct or do I need to put a fpr in my system and a fmu?

An FMU works the same as a Regulator so yes, you can use the FMU as your regulator. The only catch is to make sure that it's set to a 1:1 ratio.
