★ Authentic early type fuel tank filler cap as used on the first production series. This smaller cap was replaced in September 1942 by the larger 4" model to enable faster refuelling from jerrycans in combat conditions.
Application
This early type filler cap fits fuel tanks with small filler neck as used on early military jeeps produced from November 1941 to September 1942 (serial numbers approximately 100001 to 174738). Note: this is NOT compatible with the later 'large cap' tanks introduced from September 1942.
Installation notes
Check the diameter of the filler neck on your fuel tank. Early tanks have an opening of approximately 2" diameter, later tanks 4" diameter. The caps are NOT interchangeable between these two types. The opening in the driver's seat also differs: early has a small round opening, late has a larger opening.
Compatibility
ONLY suitable for early tanks with small filler neck (2" diameter). NOT compatible with later 'large cap' tanks (4" diameter) used from September 1942. Note: many vehicles were converted to the later large cap system during their military service or afterwards — therefore always check the actual opening on your tank first.
Historical context
The early small filler cap proved too slow in practice when refuelling from jerrycans during combat operations. In September 1942, a switch was therefore made to a larger 4" opening with funnel filter, which also enabled standardisation with Dodge and GMC tanks.
