Help with 04+ C5/C6 fuel systems.

Where as with the regulator in front at the fuel rail, the fuel rail gets the fuel first and the regulator is last in line.
I might just put it in there for shiets and giggles if I'm going into the tank anyway. The labor alone is going to be well over the cost of the Racetronix pump.
I'm just trying to decide if I should go in and replace that pump and filter or not. I mean dropping down to 52psi NA is acceptable, but it probably also means that something is wrong with either the pump or the filter. Everybody that I talked to so far said I shouldn't be dropping down to 52psi with a BAP at only 460rwhp NA.
