Ideal for carbureted nitrous engines, these regulators allow you to “stack” them together to control multiple pressures with a single fuel pump. The new “Stackable Regulator” is a clean, lightweight solution, ideal for nitrous engine combinations where unique pressures are desired. SEE THE PRODUCT No longer will sportsman and professional racers have to screw together unsightly brass T’s and pipe fittings to create a so-called “fuel log”. The Aeromotive Stackable Regulator solution creates its own integrated fuel log, by utilizing a patent pending flow-through designed modular regulator body. Using a positive O-ring seal, simply bolt as many of these regulators together as needed using the provided cap screws and O-rings. Each billet aluminum, CNC-machined regulator is adjustable from 5-12 psi and is equipped with O-ring and ORB-Ports including; ORB-10 (flow-through) ports and (2) ORB-06 outlet ports. Capable of feeding single or dual carburetors and 1, 2, 3 and 4 or more stages of nitrous, all with total control of unique fuel pressures at every distribution point. For the ultimate nitrous fuel system, it’s easy to combine Aeromotive’s Pro-Stock 2 or 4-port regulators with the new Stackable Regulators, where all flow and pressure control is consolidated for a much cleaner, lighter package. Screw the combined Stackable Regulators to the inlet of an Aeromotive Carbureted Fuel Pressure Regulator, either dead-head or bypass style and control your carburetor system pressure separate from each stage of nitrous. With the new, Aeromotive Stackable Regulators you have more flexibility than ever before. These regulators are completely serviceable in the field without removing them from the car and can be combined with the Aeromotive A2000 fuel pump or the A1000, Eliminator and Pro-Series Pump.
