Same pump that we use on the Duramax with special fitttings to plumb directly into the OE lines. This should be the last lift pump you ever buy!
"Please note that this pump is a centrifugal design. It will not prime itself upon installation and requires a leak free system so as not to lose it's prime. The best way to prime/bleed it is via suction from a hand vacuum pump (Mighty vac) or oil suction gun applied to the filter drain hose." -JK
