Shock Valve Stems

[Tortuga]

Anybody found an extension that angles the stem into the space between the saddlebag and the seat and doesn't leak? If I had the tiny hands of a six year old or the fingers of an orangutan it would be easy to reach in there and twist off the cap and twist on the pump, twist off the pump and twist on the cap. Whew, I'm exhausted. I tried one extension but it leaked.
