FUEL PRESSURE REGULATOR
Fuel pressure is as important as fuel volume, particularly in fuel injection. The Victor/
Super Victor Pro-Tuner system requires that the fuel pressure regulator maintains a
constant pressure at the injectors. It is recommended that Manifold Absolute Pressure
references the regulator diaphragm to maintain constant pressure across all 8 injectors,
regardless of fluctuating manifold pressure (vacuum) level. The fuel that is not injected is
returned to the fuel tank via the return fuel line. Recommended pressure settings vary
with application. Consult your Edelbrock representative for pressure recommendations. A
typical regulator installation is shown in Figure 3.

FUEL LINE SIZES
A high pressure EFI system does not need the same size lines as a low pressure
carbureted engine. A 3/8" diameter (-6 AN) is adequate for engines to at least 750 HP.
A 1/2" diameter line should be used on engines over 750 HP.
RETURN FUEL LINE
There are three options for installing a bypass return line.
1. Use the 5/16 rubber fuel line provided with the system as the fuel return line.
