Package had everything Included for the install of the oil pump. I did have to purchase an additional gasket kit for the front cover and water pump. I did install a new water pump at the same time since I have a 130000 miles on this motor. I was on a road trip when the factory oil pump failed, the relief valve stuck open. It did free up when I ran some Marvel Mystery Oil in the motor , but I went ahead and replaced the pump anyway. I attached pictures of what the factory pump was giving me for psi and has from day one. I used to see 28 psi to 25 psi range at full temp in the winter months. It is the HD package the PSI was always on the low side due to the oil cooler. After install of the oil pump at full temp I’m seeing close to 40psi Temperatures are also running a little cooler because of the new water pump and a complete coolant flush, along with that I went with a 180 degree t-stat . All in all very happy with this oil pump, I did just install it. I don’t have any mileage on it yet but I’m sure it’ll hold up Melling is known for quality products. I’m confident it’ll hold up to the test of time. Overall the install took me 2 days but I did run into some snags. Around 8 hours per day, I did skip dropping the oil pan and front differential to get to the bolt that holds the collector in. I was able to work that bolt out at first I used a bent 10 millimeter wrench to get it loose. Then I tied some fish string to it and backed it out the rest of the way with a hook tool. Took a lot of patience but it worked. When I reinstalled it I put that bolt in the hole that’s more accessible, I added a washer so it would push the tube into the oil pump, and used a lot of red Loctite.

Installed on 2007 Tahoe 5.3 Flex. Had the hard o-ring issue on the oil pump pickup which caused low oil pressure for the first 10 minutes after cold start. In my slanted driveway idle pressure would drop to just above 0. Once the oil was nice and hot the o-ring swelled up enough and oil pressure returns to normal. Very weird issue. 156k miles by the way.Since I had to drop pan anyway to replace the o-ring I did the oil pump as well. Left in the high pressure spring. Works great! Hot idle pressure with 5w-30 at about 38lbs is very reassuring all is well. I thought I had a little lifter noise at idle. If I did I don’t now, very quiet. 55lbs or so on the highway.A little hint. Get the flywheel locking tool. The balancer bolt has to be very tight according to GM specs. Torque 240ftlbs with old bolt. Remove old bolt. Screw in new bolt and torque to 37ftlbs and turn an additional 140 degrees.Overall very happy with this pump!

Glad unspent the extra $ on the high volume pump. I used the factory pressure spring, which gives all the pressure & volume I need.

Good oil pressure and went on just like oem as long as it lasts its great

Pressure increased from 18 psi to 35 psi when car is warm and 65 psi when cold. And you still can install either of the springs that comes with the pump for higher pressure value as needed.

Chevrolet suburban 2007 muy buen producto

Definitely increased pressure while driving. Can’t say if it helps with valve train wear yet will see after some engines I have these in get freshen up. Had rocker arms and push rods chewing each other up sometimes so hopefully this helped.

This part was worth every penny and does exactly what it claims to do. I would install it on every suburban, Tahoe, and Silverado I work on in the future if they have lower than normal oil pressure. Fits like OEM and I’m not worried about the engine getting damaged or the check engine light on for low oil pressure. Excellent upgrade.
