As described, Actual melling oil pump, not a Chinese knock off in a Melling box.

I couldn't ofnasked for a better oil pump! This one works UNBELIEVABLY, motor has almost 200k miles on it and after switching pumps. My oil pressure has been outstanding! Highly recommend.

The new Version of this pump only comes with seal and pump NO EXTRA SPRING so high volume and higher pressure is what you get! This pump is more for an engine with worn cam bearings or a new built engine with larger bearing clearances and that's what I use these pumps for with great results. If you run this pump with stock clearances, you will get very high oil pressure just so you know.

I installed this pump on a 5.3 truck engine, because the truck has low pressure and this was the only component left to replace. Threw this SOB on there and BAM, okayish oil pressure... Better than before, but not great. Decided to take this ripper down the road to "prime it up". Got out to the stop sign, gave her the beans and WRAP, cam bearing decided to leave the chat. Drove 'er home. Ended up putting another used motor in the truck and i said "I just bought this oil pump, so imma use it." Transferred this oil pump from the knocking motor to the new/used motor, got it all together, and tada, 40psi idle pressure. Good buy, worked so good it knocked a bearing out and kept kickin. 10/10

Put it in a 2003 5.3 Tahoe with 170k. I put this in bc my oil pressure would drop to zero in the morning unless I kept rpm above 2k until the truck warmed up. Pretty sure the issue was the actual old oil pump oring and not the old oil pump. The old oring wasn’t torn or anything but was cylinder shaped and shrunken. I also noticed my lifters stopped making noise with this new oil pump. My truck is 4wd so I did it without removing the oil pan. The green oring that comes with this would have worked and is what the instructions called for but it’s super hard to get that oil pickup tube back on with the green oring if you leave the oil pan on. I went and picked up a felpro oring from autozone so if your doing this without removing the oil pan either go with the complete felpro gasket set that includes that oring and the other gaskets or pickup the felpro oring to save yourself some effort. I did notice the felpro oring was slightly larger than the other black oring that comes with this oil pump kit so I wouldn’t really advise using it as a replacement unless the instructions say otherwise or calls for the black oring in the first place.

Great value for an oil pump. I'd gotten fortunate to catch the lifter tick soon enough. My oil pressure switch had been shorted so I didn't see a loss in pressure, just caught the clatter noise at low rpm. I tested the pressure manually and had near zero at idle. Immediately sent to have this pump installed and restored full pressures. 180k miles, still using 5w30, and this pump maintains 30 psi at idle when warm. It's pumping 40 psi warm at road speeds, and no indication the lack of pressure damaged the cam bearings. Got lucky. 2k miles now on this pump and its doing great. I drive my Escalade across 3 states about twice a month and I've not lost faith in it. This pump is worth the money!

Fit perfectly on my 2007 Silverado 1500 (classic) LT with the 5.3 Vin code T. Very pleased. My oil pressure went way up and is now where it should be. Been driving for 2 weeks since install and no problems so far.

I've always trusted Melling parts, I've done many pump replacements and this brand has never failed me. My 06 Silverado was undergoing maintenance, a new timing belt and water pump...the original pump was working fine until I put her back together, started her up and oil pressure kept dropping to 20, than 10...if I revved it would go up than drop again..knew it was the pump. Bought this one here, high volume which is great for motors with high mileage such as mine (175k), now she's back on the road, pressure holds at 70, and full of life! Highly recommend and the price is perfect!

Puts out the volume! Works as expected. Pressure seems a bit high but a quick response from the tech department assured me that this was normal. Take the pan off! Do the job right. It's worth the extra effort. Melling has suggestions on priming but followed the instructions in the chilton manual - pour oil into the pump before installing- and it primed immediately.
