Aeromotive 13207 - MARINE A1000 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 existing 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 existing 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 the AN-10 inlet port located in the front of the regulator using a cutoff AN-
10 style fitting (Aeromotive P/N 15608 or equivalent) and o-rings.
6. Attach the fuel return line to the AN-08 bypass port located at the bottom of the regulator using a
cutoff AN-08 style fitting (Aeromotive P/N 15607 or equivalent) and o-ring. The by-pass line back to
the fuel tank must be no smaller than AN-08 size.
7. Attach the carburetor supply lines to the regulator using AN-06 style fittings and o-rings. Install AN-06
style plugs and o-rings into the outlet ports not used.
8. The Vacuum / Boost reference port is provided for fuel pressure compensation at a 1:1 rate, this is
primarily used in blow-thru centrifugal supercharged applications. In most cases this port is left open
to reference atmospheric pressure.
9. Tighten all connections.
10. Once the regulator is installed, attach a suitable fuel pressure gauge to the 1/8 NPT port on the fuel
pressure regulator.
11. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
