<<ANOTHER thought is lancair changed from the .190 cu in pump ( 40 amps @ 12 vdc @ 1000 psi) to the .327 cu in pump ( 50 amps @ 12 vdc @ 1000 psi ) What is the indication on the pump? When?>>I believe this change was specific to the Legacy.Look for a 19 in the part number (.190 => .0187 CIPR) for your pump and a 32 in the part number for the Legacy pump(.327 => .0321 CIPR).
