A filter assembly employs a bracket and a base which mounts a disposable filter element cartridge. The bracket has a bracket mounting portion for mounting the bracket to a vehicle and a base mounting portion for mounting the base. The bracket mounting portion may be offset from the base mounting portion to provide mounting flexibility. The base mounting portion has a plurality of outwardly projecting catches that engage and support a corresponding number of hangers on the base. A threaded stud mounted on the bracket is received between the hangers. A nut in threaded engagement with the stud is torqued into engagement with the base, securing the base to the bracket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the drawings wherein like numerals represent like parts throughout the several figures, a filter assembly in accordance with the present invention is generally designated by the numeral 10.
Filter assembly 10 comprises a base 12, a bracket assembly 18 and a disposable filter cartridge 14.
The filter assembly 10 is especially adapted for incorporation into the fuel supply system or lubricating oil system of an internal combustion engine (not illustrated), such as a diesel engine, for removing particulate matter from the fuel or oil and for separating water from the fuel or oil.
The illustrated filter assembly is an inverted-type filter assembly wherein the cartridge 14 is suspended generally below the base 12.
It should be appreciated that the present invention is also applicable to filter assemblies wherein the cartridge 14 is mounted on top of the base 12.
The filter cartridge 14 is secured to the base 12 by means of a retainer collar 16.
The bracket assembly 18 is fixedly mounted to the engine header or other fixed location of the vehicle.
The bracket assembly 18 consists of a plate 30 having at least one bracket mounting portion 32, a base mounting portion 34, and an upper edge 44.
A portion of the bracket plate upper edge 44 in the base mounting portion 34 defines a ledge 42 and a vertical plane.
A plurality of tabs or catches 36 project outwardly from the base mounting portion 34 at an acute angle.
The ledge 42 together with the catches 36 support the base 12.
In an alternative embodiment, the bracket assembly 18 does not have catches and the base 12 is supported only by the ledge 42.
The bracket assembly 18 is mounted to the vehicle (not shown) at a fixed location.
The bracket mounting portion 32 may have mounting holes 38 for receiving bolts or other conventional mounting means (not shown).
Alternatively, the bracket mounting portion 32 may be welded to the vehicle.
In one embodiment, the bracket mounting portion 32 is laterally offset from the base mounting portion 34
