PDR's 13mm Stupid Pump. Min of 750cc's of REAL fuel, not the jacked up CC #'s of most other performance shops, that claim their pumps put out 900cc's or more. Not for the light hearted. This is the pump that Big Bad Dodge (BBD) and many others that have set records with. Core charge applies. Core must be complete from an 94-98 12v Dodge Cummins (no industrial pumps excepted) and without damage and be in good running shape to be eligible for credit.
