1988 Buick Electras and Park Avenues built after VIN J1637630 and LeSabres built after VIN JH468816, were manufactured with turbine fuel pumps which greatly reduce fuel pump noise. Although the Electras and LeSabres use a different style turbine pump, they both have the same quiet quality.

1986 through early built 1988 Electras/Park Avenues and LeSabres, which have pump noise and could not be repaired by fuel tank isolation, or a new pulsator (Bulletins 86-6C-2 and 87-6C-6), may also use these new fuel pumps. However, because of their larger diameter, they must be mounted to the appropriate fuel sender listed above for installation.
