6. Attach the fuel supply line(s) to the carburetor(s) using AN-06 style fittings and o-rings. Install AN-
06 style plugs and o-rings into the outlet ports not used.
7. Tighten all connections.
8. Once the regulator is installed, attach a suitable fuel pressure gauge to the 1/8 NPT port on the fuel
pressure 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 fuel pump ON WITHOUT starting the car. After several
seconds, check the fuel pressure. If there is no fuel pressure, turn the fuel pump OFF, wait one
minute, return the fuel pump ON, and recheck the fuel pressure. Repeat this 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 fuel pump OFF, 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.
13. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut.
14. 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. 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 shut off the engine and repair the leak(s)!
