I see no reply as yet. Could someone tell me the size of the heater hoses required for VE ....rubber hoses specify ID. It looks to me that there are two hose sizes at the motor connection 5/8 and 3/4 ID, but the larger one is sleeved down after the first join so that both hoses end up at 5/8 ID (7/8 OD) at the firewall end. Can someone add some info please for what looks to be a great mod for looks to fit L76 covers and for a cooler inlet manifold.
