... I switched to a Mallory regulator after a local shop showed me how much more restrictive the standard Holley regulator's passages were than the Mallory's...
Brad, did you ever see any back to back improvements?
I should have phrased this differently... when I was changing from a 120 gph mechanical pump to an electric pump, I was going to run the "old reliable" Holley blue pump & regulator combination. When I said I "switched", it would have been more accurate to say I decided not to purchase the Holley stuff and went w/ the Mallory 140 Comp pump w/ matching 4207 regulator. Sorry for any confusion.

I have read where they tested a Holley Blue pump with the matching regulator and the pump would free flow 110 GPH into a bucket without the regulator and then with the regulator installed and set at something like 6PSI it would only flow 70 GPH free flowed into a bucket. So, yes the regulator does use up some of your flow potential.
That is why I started using a return line with a Back pressure regulator installed AFTER the carb, years ago.
The supply line is -8 and loops around on the right and the return is -10 on the left.
Ron is that a BG bypass reg?
Yes, It comes with the Barry Grant 220HR Pump that I am using.
Based on the BG220PS pump this pump includes a separate diaphragm bypass that mounts at the carburetor to return unneeded fuel to the cell allowing the pump to operate at cooler temperatures. Requires a -10 AN feed and return line. Includes BG Lifetime Labor warranty.
170013 BG220HR Hot-Rod Series Electric Fuel Pump
• Continuous Duty - Designed for high hp street-driven vehicles
• Flows over 220 gph
• Includes BG Diaphragm Bypass
• Draws only 8 amps at 13.6 volts
• â?"10 AN inlet and outlets
• Lifetime Labor warranty and Free Flow-testing
• Weighs only 3-1/2 lbs
• Dimensions: 5-1/4" tall, 2-1/2" diameter motor

Gee...and a stock 440 pump will give you 72 at 6 psi. Holley blue pumps are Nitrous enrichment valve pumps at best.

So I'm not sure what to say. I liked the blue pump and reg. and spent a lot of money to run the same ET. I picked up nothing...
