you need to disconnect the hoses above the fuel rails, remove the air instake hose, remove those filters on the hoses, remove the fuel lines off the fuel rails, pull the fuel rails up not sideways you may brake the injectors! the injectors do not screw on they just pop in and out of the fuel rail and engine block...pretty simple id be glad to do it for anyone free if your around elizabethtown ky, i have a ls400 1991 and i know these cars pretty well!
