Back where,the only pump is the IP.It is under the hood part,and pulls a lot of duty as the fuel pump and IP pump.No LBZ engines have the extended warr on injectors,only the LB7's have the ex warr on them.Prob double check 4 leaks,even the smallest one in a fuel line will cause undesirable operation...
