Aeromotive 13129 - EFI 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 the fuel
system pressure.
2. Remove any cosmetic covers necessary to allow access to the fuel pressure regulator.
3. Remove the vacuum line from the regulator (some vehicles do not have vacuum operated regulators).
4. 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.
5. 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.
6. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two
#10 screws, nuts and lock washers.
7. Attach the fuel line(s) from the fuel rail outlet port(s) to the regulator side ports using AN-06 style
fittings and o-rings (Aeromotive p/n 15606). If only one fuel supply line is used, install an AN-06 style
plug and o-ring (Aeromotive p/n 15626) into the second regulator inlet port.
8. Attach the fuel return line to the regulator bottom port using an AN-6 style fitting and o-ring.
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 (0-100psi 1.5" fuel pressure gauge, part # 15633). Use thread sealant when
installing fuel pressure gauge.
