It is better if it comes from the top of the heater. The air stays out of the heater if it flows up from the pressure. Either way will work though. The later models had 3/4 in. hose on the return.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
