Just a quick FYI in case you find yourself needing a harder-to-find O-ring, I found "The O-Ring Store" online. Unlike some other online o-ring stores I checked out, you can order just 1 o-ring if you need to, and they will ship USPS for $5. Other places I looked at required minimum orders of $15 or 25 O-rings, and some stores only shipped UPS Ground for $10. The first place I looked, I was going to have to spend $18 due to minimum orders and shipping. At the O-ring store, I paid $8.30 for 5 O-rings (I only needed 1, but figured a few spares would handy.) Also cheaper than driving across town, >IF< I had been able to find anyone locally with the size I needed. Had the O-rings in hand in 3 days.
