Im going to be replacing both the lift pump and ops. Could someone supply me with the part number for the '93 HO lift pump. Also, any time saving tips or recomended tools to get at that OPS.

LP for 93 at RockAuto:
AIRTEX Part # E3158
DELPHI Part # FD0009
CARTER Part # P74001
ACDELCO Part # EP158

OPS: ACDelco D1808A (no other)

Depends on the year, the OPS location is different.
