15. Carefully place each of the fuel injectors in the corresponding fuel injector bore of the Aeromotive fuel
rail.
16. Place each of the fuel rail / injector assemblies onto the lower intake manifold, ease the fuel injectors
into the injector bores in the lower intake being careful that the injector does not dislodge itself from
the fuel rail.
17. After insuring that the injectors are properly seated in the intake manifold injector bores, reinstall the
fuel rail mounting bolts.
18. With the Aeromotive fuel rail properly secured to the intake manifold, Move the fuel injector vertically
downward until it bottoms out on the intake manifold, In this downward position, inspect the upper fuel
injector o-ring (on the fuel rail side) and insure it is fully covered by the fuel rail injector bore. If any of
the o-ring is exposed, loosen the fuel rail bracket screws and adjust the installation height unit the o-
ring is no longer exposed and retighten the bracket screws. In the situation where the fuel injector has
no vertical travel, either the fuel rail brackets can be adjusted or the brackets shimmed until the fuel
injector fits freely. Do not pressurize the fuel rail until the proper fuel rail installation height is achieved
19. Using an after-market fuel pressure regulator, we recommend Aeromotive p/n 13101, 13109 or
13129, in conjunction with AN style high pressure fuel lines and fittings, plumb the remainder of the
fuel system.
Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and
removed from the vicinity of the vehicle!
18. 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.
19. With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and
around all the fuel system components and 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!
20. 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.
21. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut and attach the
vacuum line.
22. Turn off the engine and allow it to cool.
23. 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)!
