Though those 2 little snap rings right there one is the correct 1 and 1 is the wrong. 1 for my SUV it is the right pump so what it was the big snap ring was scratching my piston for my freakin brake booster and gave me a vacuum leak which would lock the brakes up within about 5 to 8 minutes of running the vehicle nobody could figure it out so I started back at square 1. Also do not let your car sit in South Dakota with humidity and not run it he'll walk a lot of stuff up. A lot other issues had to be repaired as well. But this one stumped me on this car so he ever buy an envoy and eat a masters owner pump make sure it's right snap ring South Dakota bound babies
I thought I was really losing my mind and do not know anything about mechanics anymore over a stupid snap ring
