I replaced mine with a stock GM pump. A few of my buddies run the GM High Volume pump. Some will say it's overkill but they have had no problems. I have a new spare one sitting in my garage you can have for $60 shipped if you decide to go that route. They are usually around a $100 shipped.

thanks for the fast reply elliott! does yours come with the pick up and, or the white high pressure spring ? i was thinking about that of going with the meiling casting because people say they have a thicker mount to the block so there less prone to breakage.
does anyone have the part # for the oil pump drive ??

The M155 is a nice choice for a stock pan, but using the popular M155HV (or any high volume pump) on a stock pan is not a good idea, as the pan can be sucked dry. Higher pressure is fine, higher volume is not.
I'm running the Melling select-series 10554 with the hardened drive shaft and a Canton 242T pan.
1103868 is the p/n for the oil pump drive gear.

GM white spring 3848911 to put in it for higher pressure.
GM pickup tube, 12550042.
Melling IS-55E shaft.

That is because you don't bother to UNDERSTAND things. You will **** away $110(summit price for the Select pump and pickup) on something you don't need and wont see a benefit from here and then save cheap out and try and save $100 elsewhere where it would have done a LOT of good.
Like I said above it is the standard Mellings that people have had crack.
I will also add that the stock pump is a melling, one that GM wanted to last 300K.
I have never bought a oil pump drive gear either, don't know what people do wrong to destroy them.
That is $150 I am trying to help you save, would more than pay the price difference between junk and good parts later if applied in the right areas.
