Using a machinist, the handle is cut short leaving ~40% (coming off the pump), and a female fitting incorporated into the cut end. =A0The other 60% handle (with the bulb on end) gets a long male screw mounted inside the hollow end. =A0When screwed together, the handle is solid. =A0The 60% handle then sits elsewhere (side pouch or behind the passenger front seat or cleated under the front spar lip). This opens up the entire leg area previously blocked by the handle projecting out over the spar, and also significantly reduces the presence of the handle/pump profile sitting between the seats. Without the occasional bumps on the handle, small leakage from the pump seals seems to have stopped. I sent my handle to Brad <<mailto:dl60280@bellsouth.net>dl60280@bellsouth.net>=20 and he returned it in two weeks machined and ready for reinstall.
