Metal Shavings in Fuel Eccentric

(360 LA)My fuel pump stopped pumping so i took off the timing cover to see what was up and the fuel eccentric was loose and when I took it off to check it out, I found metal shavings all in the back of it. What could the metal be from, and do I need to tear down the engine and clean everything to make sure theres no more metal? thanks
