It still has the stock fuel rails which are supposedly internally regulated as well, at 58.5 psi. I'm reading 60 psi on my gauge right at the connection to the stock rails. I can bump this to 70 psi since it should get regulated down to 58.5 inside the rail. The rails do not have a return, they just dead end on the passenger side
