LS1 water pump flow direction

I am installing a Vintage Air kit in my 69 Camaro w/a LS1. Which heater hose nipple (3/4" & 5/8") on the water pump is the outflow?

The 5/8" is the outlet (to heater) and the 3/4" is the return (from heater).

Thanks For the answer Russ!

I first called Vintage Air about this but they didn't know the answer? (I guess they have never seen a LS1 used with their one of their systems

) I then called a local Chevy dealership...they didn't know either!!

In most cases with everything.. the smaller hose will alway be the presure side.. A/C and radiator hoses if you take notice to this.
