What pressure do you have from the pump , prior to regulator? Does regulator 'upgrade' require pump up-grade as well?
Assuming you installed the regulator correctly the most common cause of low fuel pressure on this powerstroke is the Fuel pump assembly mounted on the frame rail. There should be some testing performed to determine this though. You want to address this as soon as possible. Low pressure and volume will kill injectors. Brin
