I would remove both of em and just make sure the oil end is blocked off and let her go. That metal sleeve wasn't ever meant to move in there and I'm sure that O-ring had the pump bound up internally. If that style pump can't go full travel both directions then it won't pump fuel at all. I'm willing to wager that ethanol caused the sealing ring on the end of the oil pump piston to swell and seize itself inside of the sleeve. Just one more reason I'm glad I have the fuel only pump.
