OK, i have worked and changed many engine parts, some were easy and some were hard. How the heck do I get the fuel pump back on onto my 350? I made sure the rod was up and not blocking the fuel pump "arm"(you know what i mean" but it still will not allow me to line up the bolts and mount. Does the engine need to be bumped a couple of times to rotate cam so that mechanical push rod is further in? Please, anyone a little help for this 77 blazer owner!
