ABSTRACT:
A fuel filter assembly of a type wherein a disposable cartridge element is suspended below a base is adapted so that cartridge replacement may be accomplished in a dry or spill-free fashion. A plug is dimensioned and positioned within the base and extends into the mounted cartridge to occupy a pre-established cartridge volume. When the cartridge is axially dismounted from the base, the cartridge essentially gains free volume. The free volume gain allows for the cartridge to capture any fuel which may drain from the base.
