What size heater hose?

[lt1fire]

I'm not at my truck right now, its about 60 miles from me, but I wanted to replace the two heater hoses coming from the firewall today. One is leaking and I need to at least replace that one. I just want to make sure I get the right ones from the part store before I drive down there to do it.

IIRC one is 3/4 and one is 5/8.

Yup--square bodies need 5 feet of each--5/8" and 3/4"..

This reminds me the little by-pass hose between the water pump and block on my 6.2 looked a little mushy last time I looked ,it has a kink in it,looks like someone used straight hose on it,and cut it a little too long..should address that before it starts looking like a balloon...had one pop on one of my 454's before..
