Regulator Bypass Systems

Why use a Regulator Bypass System?

There are several important reasons why a bypass system should be used on high performance fuel systems - 

1. Bypass systems allow for a constant flow of fuel throughout the entire fuel system, making the pump and regulator(s) more responsive to the demands of the carburetor(s) and engine.

2. They help maintain carb bowl pressure to within 1/2 lb.

3. They reduce pressure spiking and system pulsation.

4. Cool fuel is continuously circulated from the cell or tank to the engine.

5. Installing a bypass system enables regulator and fuel pump pressure adjustments while the engine is not running.

Regulator Mounting:
Placement and mounting of fuel and/or nitrous regulators is very important for optimum performance. All regulators should be “soft mounted” to isolate them from engine vibration. “Soft mounting” can be accomplished using rubber isolators or simply suspending the regulator from the fuel lines. In addition regulators should be mounted in front of or near the front of the engine whenever possible. This location will allow the low pressure fuel flow from the regulator to work with the G forces when the car is launched.
