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). Requires thread sealant.
11. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
12. 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.
13. 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!
14. 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 the enclosed regulator is 40-75 psi.
15. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut and attach the
vacuum line if the vehicle has one. If the vehicle is not equipped with a vacuum line, leave vacuum
port open to atmosphere. Blocking the vacuum port will yield poor regulator performance. If vacuum
port fitting becomes lost or broken replacement fittings can be purchased (part # 15630).
16. If 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 and remove the fuel pressure gauge.
17. Test drive the car to insure proper operation and re-check the fuel system for leaks. If any leaks are
found, immediately shut off the engine and repair the leak(s)!
