Southeast Florida | If its a 60 series or older this is all wrong! This is for a 8X00 and newer setup.
You should have 4 ports on the back if it's factory or dealer kit. If you look on the casting one will have "P" for pressure, "R” for return (which is a pressurized return ahead of the charge pump), "S" for signal (to send pressure to the pump on requirements) and "T" for tank which is use for a non pressurized return usually case drain. If you dump straight into the T port you'll starve the system because the charge /lube pump only makes about 5 GPM. If you need to put a variable flow control on the power beyond it needs to be a special valve for a PFC system. There are other requirements also to deal with the “S” port. You need a shuttle valve plumbed in for pump signal pressure. It’s real easy to do but not every hydraulic shop has knowledge of how to do this and will give a funny look.
