3.0.8 Oil filter and bracket
For most of production, the standard GPW oil filter was a purolator cartridge type. Certain units may have utilized a Fram filter assembly after mid 1943.
The Purolator filter is identifiable by its dome shaped cover, marked COVER ASSEMBLY 25791 PUROLATOR PRODUCTS INC MILITARY STANDARD FILTER There are three decals on the filter assembly, a cover decal describing servicing procedures, a body decal with a script “f” and the part number “GPW 18660” and one marked PUROLATOR PRODUCTS INC CASE ASSEMBLY-26708 USE JUNIOR ELEMENT. The decal background is properly a deep red color as compared to the incorrect orange decals commonly available today. The oil filter body is stamped INLET in 1/4” block letters in silver paint above the inlet port. The body, cover and cover bolt of the Purolator filter are painted an eggshell finish black enamel. Oil filter bands are made of 1/8”x7/8” steel, slotted mounting holes have rounded ends. Bands, screws and square nuts are painted black.
Flex oil lines are lacquered cotton braid cover (not rubber).
The oil filter bracket is painted gray engine color. The filter assembly is attached to the oil filter bracket with S7 or S2* finished bolt, lock washer and flat washer.
* Both S7 and S2 hardware appear in factory photographs.
