SS Fuel Pump / Static Regulator / Bypass Regulator

I have the SS fuel pump P/N 11203 and a static regulator P/N 13205.  My new engine will make more than 750 FWHP and your catalog says that’s more than the SS pump will support, unless I use a bypass regulator.  Is this true, and how can a bypass regulator make that much difference?

Yes, it’s true. Electric pumps flow more at lower pressure, so a bypass regulator increases flow compared to a static regulator. While both regulators maintain 7 PSI at the carburetor, a static regulator causes the pump’s internal bypass to open at 15 PSI, reducing flow. A bypass regulator keeps pressure at 7 PSI, allowing the pump to flow more and support higher horsepower. Switching to a bypass regulator maximizes pump efficiency and performance.
