Pick-up tube o-ring I'm getting ready to change my cam in my 2000 c5, and am trying to understand what makes the difference in the pick-up tube o-ring. There are two different numbers ( 12557075 & 12557752 ). Is it the pick-up tube or the pump body that makes the difference? I will be installing a stock ls6 pump on a ls1 engine. If the difference is the tube, then it seems to me you would stay with the ls1 o-ring (12557075). Any help would be appreciated. 
I just changed the pump,oring and timing chain in my 98. I do not have the part no. on hand,what I did when I did this upgrade is I asked for a 03 Corvette Oil pump and a 05 GTO Timing Chain,which is the LS2 ,these are the upgrade replacememts that are being used on our 
cars from the dealers. The LS2 Timing chain is a nice upgrade, and fits perfectly, cost is around 30.00. Hope this helps you.
