That's a bushing.....it threads in the top of the pump and holds the barrel and plunger down.

NO you don't need a new pump, and YES is if fixable. It's a $5 o-ring, but the barrel and plunger is timed. Need to loosen half of the bolts on the side plate, and drain the fuel from the manifold. Also need the CAT splined socket to remove the bushing, and re-torque to 200 ft/lbs. Turn key switch on, drop the CAT timing pin in the hole, and rubber strap the throttle all the way back.

If you want to attempt it, me or someone on here can walk you through it. Not a big deal at all. When re-assembling just need to have a can of Brake Clean or Ether and make sure your hands are perfectly clean. If not, you will have fuel in the oil in a very short period of time.
