Holley 162-590 C5 style regulator
Anyone here actually using the Holley 162-590 or 162-591 with a pump flowing 255, 340 or 450 lph?
The regulator specs say it is not recommended for pumps flowing over 450 lph.
I just went back from a fuel rail mounted regulator to a C5 regulator mounted where the OEM fuel filter is located. This change due to overheated fuel related problems. My C5 regulator yields 64 PSI at idle and 58 psi under load and up to 7000 RPM. I am looking for a constant 58 PSI supply pressure. Iwould not want to find out that the Holley is just another C5 regulator with its associated fuel flow limitations.
Thanks for your comments.

It looks like a near exact copy of the C5 regulator/filter with possible minor spec differences.
