    • Happy with this oil pump
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. 🚗 ... show more

    • Great oil pressure 5.3 lm7
Worked great on a 5.3 lm7 holds about 70 psi cold start and 60 warm would recommend this part. Always be sure to take the cover off and inspect inside before installing though!

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. ... show more

    • Instant oil pressure.
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.
