14. Place clean shop towels around the injectors to catch any gasoline that may be spilled
during their removal. Remove each of the injectors from the manifold by gently pulling
upward on each of the injectors.
15. Remove the old o-rings from the fuel injectors, inspect the injectors for any dirt or debris
and clean if needed. It is suggested that the old o-rings be replaced, contact your local
auto parts store for replacement o-rings.
16. Coat the new fuel injector o-rings with a light oil to ease installation.
17. Carefully install the new injector o-rings on the injectors.
18. The backside (the end closest to the vehicles firewall) of the Aeromotive fuel rail should
have a port plug installed in it. Install the appropriate union fittings and o-rings in each
end of the fuel rail, we recommend Aeromotive p/n 15605 for AN-06 or Aeromotive
15607 for AN-08. The front of the fuel rail on the right side (passenger) of the motor will
be a close fit, we recommend using an AN-08 90-degree Male ORB hose end,
Aeromotive p/n 15665.
