A variable wash flow filter assembly includes guide that is operable to guide a wash velocity control cone between a minimal position and a maximum position. The guide defines at least one activation deltaP window downstream of a conical gap between the wash velocity control cone and a frusto-conical wash filter. The fuel flow through the conical gap and the activation deltaP window is operable to position the wash velocity control cone between the minimal position and maximum position to selectively split a fuel flow through an inlet into a burn flow through a thru flow port and a filtered flow thru the frusto-conical wash filter and filtered flow port.
