M295HV High Volume Oil Pump Compatible with Escalade Chevy Avalanche Silverado Suburban GMC Savana Sierra Yukon 4.8L 5.3L 5.7L 6.0L 6.2L

For the price, I was skeptical. But after using it for awhile they hold pressure great. Can compare to a Melling oil pump for 1/4 of the price. Make sure you run an extra quart of oil since it’s the high volume unit so you don’t have oil starvation at higher rpm.

Had a silverado 6.0 with 200k miles on it oil pressure was south of 40 psi all the time and worse at startup ( 10-15 psi when cold). Installed this pump and now its 65 psi at start up cold and around 50 psi hot with 5w30.

Nice amount of volume to my main and cam bearings. Make sure your oil pan is 6 + quarts

I mean it works. Should’ve went OEM

You only get 8 to 15 psi pressure very disappointing

Part was easy to install. Got this pump for the good price and because it says it was a HV pump but after the first week my pressure was at 15 psi.

Did a cam and heads package had to no oil pressure from the start

It only lasted 10 min in new motor build
