Just replaced both of mine, it's 1/2" hose & 5 feet will do it!

May I ask how you dealt with the right angle hose to heater connection and are the heater connection close to the firewall or the dash?

No issue, just a nice big bend... there's plenty of space.

Update FYI:
Total length of heater hose needed: 5 feet (after stuffing extra hose length under dash, I had 1" extra leftover)
ID: 1/2"
Inlet hose length (right side): Water Pump Housing to heater core: >36",
-can be longer if you allow extra length under dash, I noted hose end to be damaged due to age at the housing.
-cutoff damaged end (after 20 yrs) and use again!
Return hose length (left side): Thermostat housing to heater core: >19"
- As above
Picture below are the heater hoses I removed.
The extra pieces of hose:
- to the right on the top (right ) hose was the 2" I took off to pull the hose through the grommet in the firewall.
- to the right on the bottom (left ) hose was the 1" left over from the 5' hose (not showing the 2" cut off piece)
