Hello Kevin- Your idea about a sleeve is correct, and common. Any good
machine shop can sleeve it for you without cause for concern. You're also
right about the seal not holding up... if it isn't SMOOTH, it will leak
just like the sieve you envision. LMK if you need manufacturers' reps for
the sleeve. Good luck, and rest easy.
