Melling-10295 Oil Pump, Wet Sump, Internal, Standard Volume, High Pressure, GM LS-Series, Each

Ventured to replace my old pump with this one for my GM LS engine. It works well during daily drives and even on long trips. The installation was straightforward, and I appreciate how reliable it feels at high pressure. Definitely a good upgrade for anyone needing a standard volume, wet sump oil pump. 🚗

I installed this pump in a 2006 Silverado that had low oil pressure at idle. It primed instantly & produced almost 60 PSI of oil pressure. There is a video from Melling that shows how to properly prime it before installation.

It works like it should !! Over 40 on idle I’m super happy with the results.

My oil pressure sits at 60 on start up and 40 when the car warms up. Normal driving it’s around 50-55.

I had a lifter fail on my 5.3 vortec 03 suburban. I pulled both heads, replaced all the lifters, springs and valve guid seals and put in a stage 2 cam. I had decent oil pressure before so I left the oil pump in place. I thought I dropped a bolt down the cam valley though so I pulled the oil pan and pick up tube. I reused the o ring on the pickup tube and that was a terrible idea. After everything was done I started the truck and had 40psi at idle but after the engine warmed up it would drop to less then 10 at warm idle. I decided to just order a new oil pump and because of the choppy idle I opted to up the oil pressure. This pump performs great! I used the installed spring, instiall the bolts hand tight and then spin engine 360 degrees to align the pump and then torque the bolts tight. I primed it by cranking the engine with the injectors unplugged on each valve cover. Once I plugged the injectors back in and started the truck it built pressure instantly. I attached 3 photos, one showing cold idle, one showing cruising and one showing warm idle. Oil pressure peaks just under 80 psi on hard throttle and never drops under 40 now. Very happy, hopefully I get another 240,000 miles out this engine now.

Served its purpose

Amazing oil pump very good pressure worth every penny if you care about your engine

Somewhat pricey but well worth it! Definitely a pain to install unless you drop the oil pan but can be done (there’s a YouTube video one it) in case your wondering they add the lower and higher pressure springs in the kit so you can run 75+psi out of this pump.

Great Melling part. Did AFM delete on my 08 Avalanche and decided to replace the oil pump while I was in there. Swapped out the high pressure spring for stock one, but in retrospect I could have just left the spring in. Oil pressure is within spec. 20 psi at hot idle and 10-12 psi increase per 1000rpm

Buena calidad

Great product but packaging and delivery disappoint. No packaging to protect product and was just left in driveway in full view. So disappointed.

قام الفني بتركيب المضخة لكن قام بإزالتها مرة اخرى والسبب حسب قوله أنها أضعف من المتوقع.

I now have oil pressure again...Yay
