Holley/Demon Carb stumble
I was thinking 'bout the pumps but that's fine.
Here's what they have on the 4309 regulator in this catalog.
Also the promo/tech on their regulators from the inside back cover.
Under that are a couple of pump delivery graphs also from the inside back cover.
Vertical axis is % of free flow. This is an in-line restricting type, not a return type.
