Not much to say on it's performance because I had to return it & swap for stock volume. It's a '00 GMC Jimmy 4.3 V6 4x4 with the cast aluminum oil pan. Couldn't seem to get the proper 3/8" clearance between pan & screen - couldn't even get 5/16" - so back to the store it went. Figured the HV pump would give me a bit more engine life, since I cheaped out and skipped on doing the crank & big-end bearings, but it's a daily driver - mostly stock except it's got an Edelbrock carb instead of FI, so don't really need the HV anyway. Will be installing the stocker (Melling) in it's place.

Changing the oil pan gasket, so in thinking if upgrading the oil pump, will the stock oil pan work? Getting new water pump, slightly bigger radiator, ac delco plug's, msd 8.5mm plugs, new distributor cap n rotor in other words im changing things out here n there with slightly performance parts. Nothing crazy just slightly upgraded.
So my question, what size oil pan should i use? Got a total of 5"drop in front. 2"lowering springs, 3" lowering control arms....

Hi Star, I'm glad to help you! To check the exact fit application for the part number M155HV, please provide us with the correct engine size of your vehicle.
what is the high end pressure of this pump
Product Owner - scottalanchannells
Depends on the engine cold 65 to 80 psi depending, and warm never seen less then 45psi
Product Owner - carmes2936
Running 40-45 at idle and 60-65 at 55MPH.
Product Owner - rlhul
no different then stock PSI. The difference is volume. You get more flow out of this pump then a stock pump. its about 25% more.
Would this part fit on a 97 2wd s10 with the 4.3 vortec
