3. Remove any cosmetic covers necessary to allow access to the fuel pressure regulator.
4. Remove the vacuum line from the O.E. fuel pressure regulator.
5. Disconnect the fuel return line from the bottom of the O.E. fuel pressure regulator.
6. Place shop towels around the regulator to catch any gasoline that is spilled during this step of the installation.
Remove the two 6mm mounting bolts and carefully remove the regulator from the fuel rail.
7. Apply light oil to the o-ring supplied in the Aeromotive package.
8. Place the o-ring in the o-ring gland located between the two mounting holes on the regulator.
9. Install the new Aeromotive fuel pressure regulator onto the fuel rail using the two supplied mounting screws on
torque to 9 ft-lbs.
10. Connect the vacuum line from the O.E. fuel pressure regulator to the barb fitting located on the side of the new
Aeromotive fuel pressure regulator.
11. Reconnect the fuel return line to the bottom of the fuel pressure regulator. If your application utilizes AN style
braided return line, the barbed fitting in the base of the fuel pressure regulator may be replaced with Aeromotive
p/n 15606 for AN-06 return lines.
7. Once the regulator is installed, attach a suitable fuel pressure gauge to the fuel system schrader valve or the 1/8
NPT port on the fuel pressure regulator.
8. Reattach and reconnect any peripherals that were removed to gain access to the regulator.
9. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and removed from
the vicinity of the vehicle!
10. Reconnect the battery and turn the ignition to the ON position WITHOUT starting the car. After several seconds,
check the fuel pressure. If there is no fuel pressure, turn the ignition key to the OFF position, wait one minute,
return the ignition to the ON position, and recheck the fuel pressure. Repeat this ignition OFF and ON procedure
until the fuel pressure gauge registers fuel pressure.
11. With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and around the
Aeromotive regulator and all fuel lines and connections near the regulator! If any fuel leaks are found,
turn the ignition key to the OFF position, remove any spilled fuel and repair the leak before proceeding!
12. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the engine and
adjust the regulator to the desired fuel pressure. Turning the adjustment screw clockwise will increase fuel
pressure. OEM regulators are typically set at approximately 43 psi, without the vacuum line attached. The fuel
pressure adjustment range for this regulator is 40-75 psi.
13. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut and attach the vacuum line.
14. Turn off the engine and allow it to cool. If the schrader valve was utilized to check fuel system pressure, remove
the fuel pressure gauge and replace the cover on the schrader valve. If the 1/8 NPT port on the Aeromotive
regulator was utilized to check fuel system pressure and you do not want to keep the fuel pressure gauge on the
vehicle, relieve the fuel system pressure as instructed in the appropriate vehicle service manual. Remove the fuel
pressure gauge and reinstall the 1/8 NPT pipe plug into the regulator gauge port, using thread sealant.
15. Test drive the car to insure proper operation and re-check the fuel system for leaks. If any leaks are found,
immediately shutoff the engine and repair the leak(s)!
