Thank you for choosing the Atomic Fuel Pressure Regulator. This is recommended when using the
Atomic Throttle Body EFI and Atomic LS EFI systems.
Parts Included:
1 - Adjustable Regulator
1 - Regulator Parts Bag includes:
1 - Regulator Mounting Bracket
1 - Brass Hose Barb Fitting
1 - Stainless Steel Pipe Plug
2 - 10-32 x 0.375 Button Head Cap Screws
1 - High Pressure Fuel Hose Clamp
CAPABILITIES
The Atomic Adjustable Regulator is configured for a single -6AN inlet, and dual -6AN outlets (for regulator-
to-tank line routing flexibility). The recommended operating range is 15-90 psig (pounds per square
inch gauge). The maximum recommended flow rate is 500 liters/hour (2.2 GPM). The vacuum/boost
compensation ratio is 1:1.
RECOMMENDED PLUMBING SCHEMATICS
Use the schematic below as a guide when installing the regulator in conjunction with an Atomic throttle
body EFI system (Figure 1). There are two possible connection points on the throttle body unit, one of
which will be the fuel supply in an operational system. DO NOT “tee” into the supply line and leave the
-6AN port plug installed on the throttle body. Remove the -6AN port plug from the throttle body and route
fuel from that port to the regulator inlet port. The hose length between the throttle body and regulator is
not critical, but generally speaking, should be kept to a minimum.
