Detailed Description

Delphi MF0006 is engineered as a mechanical fuel pump replacement for classic GM applications that use a 3 line pump configuration. It is listed for a wide range of Buick LeSabre, Buick Riviera, Oldsmobile Cutlass, Oldsmobile Delta 88, Oldsmobile 98, Pontiac Bonneville, and related models across the 1970-1990 model years. This part cross-references Airtex Fuel Pumps 41567 and Carter M6109 for the same application.
