Not sure how many of you run a cabin heater but I've installed a Vintage Air system and I'm just about to do the the hoses for the heater. The proposed routing involves considerable 'rises' and 'falls'.

Am I correct in assuming that, like a garden hose, as long as it is an even 5/8" bore there shouldn't be issues with air pockets? Basically, should the initial air get pushed out of the system and into the motor (LS1) where it's vented normally to the radiator and overflow tank? Thanks.
