Posted July 8, 20204 yr comment_602307 Anyone know what size hose this is from the throttle body to the AAR on the 78 I thought originally it was 5/8” but that seems way too large. Also anyone have a good hose recommendation it’s pulling vacuum can I just use heater hose though?

July 8, 20204 yr comment_602315 Try Mishimoto 1/2” PCV/CCV hose. It’s a tight fit but worked on my 78. Link to comment https://www.classiczcars.com/forums/topic/64234-aux-air-regulator-hose/#findComment-602315 Share on other sites More sharing options...

July 9, 20204 yr comment_602366 If you haven’t already, check out the Mishimoto stuff. Glad it worked for you. Hard to find any heavy hose thats not steel braid.
