The RG hydraulic pump rebuild kits seem strangely difficult to locate. There is some good info in the Lancair community. They use the same pump/cylinder system that Velocities do. According to their experts, the only non-standard part in the pump rebuild kit is the poppet valve, so you only need a rebuild kit if the poppet valve is leaking. Usually, you just need these standard O-rings from McMaster:

013-90, Spool Seal (013N90)
014-90, Check Valve Body seal (014N90)
908-70, Hex Plug Seal
908 Durometer 90

For more info, see Lancair builder Chris Zavatson's site: http://www.N91CZ.net

Linked below are his diagrams, explanations, and instructions for rebuilding the hydraulic pump and cylinders.
