This is an 8.3L C-series Cummins oil pump, modified to fit 12v and 24v engines. It offers 42% more displacement than the stock 12/24v oil pump, providing more oil flow and pressure for modified engines. Warning: The factory suction tube is too small for safe operation above 3500 rpm with this oil pump. We offer an oversized pickup tube for those who want the ability to rev above 3500 without risking cavitation and oil starvation problems.
