I am not running a regulator, because of the red pump. Where is it adjusted at?

Aaaack! The pressure relief valve is externally accessible, not externally adjustable. Supposedly it's set at 7psi at the factory.

Sorry, never used a Holley Red. Just Holley Blues or Mallory pumps with regulators. 5.5 psi seems low though.
