I have a ported LS6 pump I got from TSP that I'll be installing shortly. It came with a blue o ring. I read on here someone used a blue one instead of the red one and his oil pressure was all jacked up. Anyone have any insight on this, or maybe someone from TSP can give me some info before I get a chance to call.

Thanks

 

IF your using the truck pickup use the blue/green lookin one like in this picture..Its what i used when i put my ported ls6 pump on..

 

I'm assuming it's the truck pickup.

 

The truck one is pretty long compaired to the car one..
