    • Great oil pump would recommend
This has been a really good oil pump. Have had it in for over a year. Maybe two. It was a fraction of the price than the local parts store and it has 60psi at idle and 80 under load. Great oil pump

    • With a cam
I put this pump in my 5.3L when I replaced my cam. I went from 20 psi @ 210° idle, to 65-70 psi @210° also at idle! And dont stick it in dry folks, you should always get it good and primed up with some, assembly lube... great pump tho, I'm very happy with it!

    • Works great
I have an 08 Yukon XL with AFM. The AFM lifters began causing dangerously low oil pressure. After installing this pump the pressure stays around 60 psi unless the lifters act up but it still maintains 20 psi when lifters are collapsing. In the process of doing actual AFM delete.
