Check your new fuel filter,if it comes with white nylon retainers,it's the same as my Olds. First relieve the fuel pressure at te schrader valve on the fuel injection rail. Grasp the black plastic connecter on the fuel line,push in slightly toward the filter,and squeeze in the 2 white retaining tabs, pull off line. There should be o-rings,make sure they are in place,or it'll leak. Hank
