The enclose Aeromotive regulator utilizes 2 o-ring sealed AN-12 ORB style inlet/outlet ports, and one o-ring
sealed AN-12 style ORB bypass port. This requires ORB-12 to AN male-flare port fittings to be used, such as
Aeromotive P/N 15612 or equivalent. These regulator ports are NOT PIPE THREAD and the fittings utilize NO
THREAD SEALANT.
The enclosed Aeromotive regulator is designed to be used with high flow, high pressure, mechanical fuel pumps
similar to Aeromotive P/N 11105 or larger. It is also suitable for high flow/high pressure fuel systems utilizing
dual Eliminator (p/n 11104) or dual Pro-Series (p/n 11102) fuel pumps. Bypass restriction measures ½” or 0.500”
on the ID. Recommended fuel pump flow range from minimum 300-GPH (5-GPM) and up.
The Vacuum / Boost reference port is provided for fuel pressure compensation on a 1:1 ratio with manifold
pressure (vacuum or boost) in PSI. This port must be connected to the intake manifold, in the plenum (behind
the throttle body) for proper vacuum/boost reference.
Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.

The following steps are typical of most installations:
1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve the fuel system
pressure.
2. Remove the vacuum line from the existing regulator, if equipped (some vehicles do not have vacuum operated
regulators).
3. Place shop towels around the regulator to catch any gasoline that is spilled during this step of the installation. Remove
any regulator mounting hardware and connecting fuel lines, then carefully remove the regulator.
4. Find a suitable place in the vehicle’s engine compartment to mount the Aeromotive regulator. Using the supplied
mounting bracket as a template, mark the bracket mounting holes to the mounting surface and drill to accept a #10
screw.
5. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two #10 screws, nuts
and lock washers.
6. Attach supply line(s) using high-pressure AN line to the ORB-12 inlet ports located on either side of the regulator. Use
ORB-12 to AN male port fittings with o-rings. Block any unused supply ports using an ORB-12 port plug and o-ring.
