derotoreut Roto Reuter thats the name... Join Date: Feb 2010 Location: Darien, NY Posts: 1,853	Please help confirm my heater hose connections I'm working on my 5.3L LM7 swap and need to know which heater hose is which. I believe the 5/8" hose is the supply (out) to my Vintage Air heater control valve & heater core. This would make the 3/4" hose the return (in) back to the engine from the heater. Is this correct? __________________ ~ Dan My 70 K10 SWB build:http://67-72chevytrucks.com/vboard/s...d.php?t=782232 My 71 SWB build:http://67-72chevytrucks.com/vboard/s...d.php?t=651394 1970 SWB Fleet K10 4X4, 5.3L LM7, 4L60E, Dakota Digital RTX, Vintage Air, Ididit tilt 1971 SWB Fleet C10 - Original SWB Arizona truck, new custom restoration project "Kick out your motor and drive while you're still alive - kick it out!" - Heart 1977
