""" That was one of our concerns with the filters and EFI pumps behind the aft spar on the IVP... the filters being the first thing in line after the fuel makes its way into the cabin from the wing. We installed ball valves in each wing root fairing, oriented so the valve cannot be shut off with the access panel in place... pull the access panels, turn the valve handles down through the openings and voila! no fuel coming in to the filters so we can service them. We used big ball valves, probably 1/2"NPT fittings, so there'd be no restriction caused by them. FWIW.
