i’m looking over the motor i bought and need some help with the coolant line. I have two nipples on the heatcore line. Were does those nipples lead to or do i loop them together.

2)Do i have to use the vaccum lines of the tb to run canister or Can it be blocked off. If blocked will it affect performance. Btw if it matter my coolant lines on my tb has been bypassed.
