Part Number: 40446 (AC Type 40446)
Type: Mechanical Fuel Pump (Crimped Canister / Inline 6-Cylinder)
Replaces OEM Reference: GM 6440446, GM 6416502, GM 6440616, GM 6440792
Note: This pump is the "Crimped Canister" (non-serviceable) style often used as a service replacement for 1963-1965 models and original equipment on 1966-1975 models. It fits the Chevrolet-designed Inline 6 engines (194, 230, 250, 292). It typically does not fit the Pontiac OHC 6 engine (which uses a different specific pump, AC 40494, though some sources show interchangeability on later 250ci standard OHV versions).
