These are o rings you need, the others i bought at tractors supply in an assorted pack.
Just bought the rings from oringsandmore. Is this the assortment you were talking about from TSC?
Double HH O-Ring Kit, 72 Piece at Tractor Supply Co.
#6 on this exploded view are what leak. To much stress on these orings from the movement! Crap design!!
On another note my FEL controls was not working correctly when the valve/pump was leaking. The joystick would not return by itself. I guess it needs full pressure to work right.
