Pontiac fuel pump with gasket for the 1972-75 models 6.6 ltr Pontiac 400 & 455 V8 with or without air conditioning (or originally fitted with AC).
Long Tank for those needing 4bbl Reserve as factory.
How to ID a PONTIAC V8.... your starter is on the LHS.. although GM has discontinued this pump.. its now a perfect aftermarket brand.. looks the same but without the "AC" cast on the side.
