Hey guys, I am rebuilding my fuel bowl and I was taking the screen out of the fuel pressure regulator. I dropped the reg on the bench and the screen was almost out and it popped out.

I am not sure if there is anything else that came out from behind the screen. Is there a check ball that goes in there or anything? Anyone got a schematic that shows the regulator parts? Thanks

Thanks, turned out I did lose the check ball, I was able to find it luckily. Got all the glow plugs replaced, had 4 bad, Autolites of course, replaced all of them with Berus. Did the FPR shim also. thanks again for the fast response!!!
