No, they can outlast the engine. One cup is retained by the bolt, the other spins around it. It is lubricated by oil spray from the camshaft gear. So the part that the fuel pump arm rides against is actually spinning- very little friction. You may have missed the locating tab, or thought it was tight enough, or accidentally clamped both cups solid. Don't feel bad if you messed up, we all do it at least once. But if it checks out, look at the fuel pump. I have had brand new ones be bad out of the box. These days they can sit on a shelf a LONG time.
