Recently my Eldo (Dora) developed a coolant leak right at the neck of the surge tank. Due to this (and 135,000 miles) I've decided to go ahead and replace it, as well as the radiator, hoses, water pump, tensioner and belt... I.E. pretty much everything I can get my hands on from AC Delco.
My question is, how many heater hoses are there? I was sent a total of 4, and can only find 2. The one from the bottom of the surge tank, the one that goes from the metal tube connected to the surger tank to the heater core and???
Does anyone have a diagram that shows the locations and/or routing of said hoses?

I'd really appreciate the help guys.

These 2 hoses in particular are the ones I'm asking about... Do they replace the metal coolant tubes?
