Intake Manifold Heater Hose Connection

George, Thanks for the offer. I used 1/2" hose almost to the heater core, then a plastic hose adapter to go from the 1/2" hose to the 5/8" hose to hook up to the heater core. They have these shrinking type hose clamps that I used on the adapter. I have some sleeving to over it all so it won't be seen.
