Need to know the inlet and outlet lines for the heater hoses coming from firewall. I do not want to put them on wrong.

Hello, I am Danny.

I have attached a picture to answer your question. The left pipe (#1) is the Inlet and attaches to the intake manifold on the engine the right pipe (#2) is the outlet and attaches to the water pump. Hope this helps!
