The following steps are typical of most installations:
1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve any fuel
system pressure.
2. 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.
3. 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 and drill to accept a
#10 screw.
4. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two
#10 screws, nuts and lock washers.
5. Using a Y-block, split the supply line into two AN-08 lines and feed one side of each fuel rail. From the
other end of each fuel rail run an AN-08 line into each of the AN-08 ports on the regulator using the
two supplied AN-08 fittings and o-rings.
6. Using the AN-08 port plug and o-ring provided, block off the unused AN-08 port on the regulator.
7. Using the AN-10 port plug and o-ring provided, block off the AN-10 port on the front of the regulator.
