Alright, I'm in the process of putting a 6.0L LQ4 in my 1995 impala ss...but I have a question. The PS pump that came with the engine came with 3 outlets...one being for the hydroboost I'm guessing. Is there anyway I can use this without the hydroboost function? I'm also not completely sure which is the return fitting either...I'm guessing the pressure side is the threaded lower hole. Any suggestions?

 

I am converting to hydroboost on my truck that originally didnt have it. want to swap PS pumps?

 

Only difference external is one extra return port. Just cap off the one the points upward. The screw in is the pressure side.

 

Use the lower return tube for your return from the cooler.
Cap the Upper tube. like KYSilverado said.
