Camshaft and eccentric ring 1 or 2 pieces of key stock

Have you put the bolt on and torqued it down yet? Mine did not look like it would engage the fuel pump centric but once I torqued it down all is good. Like Rusty said the cam gear is probably not on all the way back. You can loosen the bolt take it off after you have torqued it the first time and then place the centric back on and you should be able to see it in the slot on the centric. If your cam socket moves so much that you cannot do what I just described something else is up. Hope this helped
