22. Connect one AN-08 90-Degree Male ORB hose end to the rear of each fuel rail. Plan a route
between the two hose ends, measure the lengths of fuel line needed. See section titled Hose and
Fitting Assembly for fuel line assembly instructions. Once the hoses are assembled, ensure there is
no debris in the hose and install them.
23. Reassemble the vehicle using the reverse of the foregoing removal procedure.
24. Remove the 1/8 NPT pipe plug from the fuel supply adapter tee fitting and attach a suitable fuel
pressure gauge if desired.
Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
33. 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.
With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and
around the Aeromotive fuel line adapter, fuel rails, all fuel lines and connections! If any fuel leaks
are found, turn the ignition key to the OFF position, remove any spilled fuel and repair the leak
before proceeding!
34. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the
engine.
35. Turn off the engine and allow it to cool. 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, using thread sealant.
36. 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)!
