Yep goes back as it came out just go slow sliding the engine back toward the transmission if it stops check that the input shaft is aligning with the clutch bushing, I used a hyd jack under the transmission to raise or lower it as needed,now is the time to put a new hydraulic pump belt on and its a good idea to place a spare belt in the hogs head. Sounds like you'll bet back up and running in short order. Did you have to go oversize on the piston and bore? How was the crank did it clean up or did it have to be ground under?
Nothing wrong with the plastic fuel pumps they have been in use for many years now.
