Aeromotive 13209 - DOUBLE-ADJUSTABLE BYPASS REGULATOR - Manual (Page 2)

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. Attach the fuel supply line to one of the AN-08 ports located around the perimeter of the regulator
using AN-8 style fittings and o-rings.
6. Attach the fuel return line to the AN-10 bypass port located at the bottom of the regulator using a
cutoff AN-10 style fitting (Aeromotive P/N 15608 or equivalent) and o-ring.
7. If you are not using a fuel log, attach the fuel supply line(s) to the carburetor using any of the
remaining AN-08 port around the perimeter of the regulator body using AN-08 style fittings and o-
rings. Install AN-08 style plugs and o-rings into the outlet ports not used.
8. Tighten all connections.
9. Once the regulator is installed, attach a suitable fuel pressure gauge in the fuel system.
