Remove the cable from the negative terminal post with the anti theft activate off on models with Delco LoeII audio system. Remove the fuel inlet and outlet lines using two wrenches: An open-end wrench on the fuel pump and a flare-nut wrench on the fuel line fitting, you do not want to mar the pump and connections with a conventional wrench. , then remove the fuel pump mounting bolts, the pump, and the gasket are next. For the V6 engines, the next step is to move the pushrod whereas, for the V8 engines, it is necessary to take out two bolts-it is necessary to take out the fuel pump adapter gasket alongside it-and then eliminate the pushrod. Remove all traces of gasket material and sealant from the fuel pump, adapter, and engine block, apply heavy duty grease on the pushrod to lock it up and then fit it in the engine block. On V8 models, screw the adapter plate with a new gasket and then place the pump with a new gasket on it and used gasket sealant on the screw threads. Last but not least, fasten the fuel lines, kick the starter, and, if there are no leaks, you are good to go.
