Re: Heater hose
I believe hot coolant is supposed to flow out of the intake manifold, through the 5/8" hose, and into the heater core. The outlet/return of the heater (3/4" hose) is hooked to that fitting on the water pump.

Re: Heater hose
Correct you want the hotter coolant coming from the intake manifold to flow through the 5/8 hose to the core, then return to the water pump through the 3/4 hose. I've seen this in reverse and the heater will have problems.

Re: Heater hose
Sorry forgot to post the measurement previously. Mine are 36" long. You could probably get away with them slightly shorter.
