The pumps have a ring Rebuild Kit (Lancair part# HC-490) which contains three O-Rings: O-Ring Hand Pump plug (Item 33X3) O-Ring Polypak Hand Pump (Item 4615.1870-0875) Wiber Hydralic Cylinder Main Gear Down (Item 940-3) This part# HC-490 (~$10) is not listed on the aerocraftparts.com website. Michelle provided this quickly. Replacment of these rings does not look complicated. I'll be installing these rings shortly, and will have some follow up reports in a couple months of use.
