What size line???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm going to re-do some plumbing on my 'burb and thought I'd add a dual gauge to the front. I have this Airride gauge but dont know what line goes to the fittings.

Can anybody help me out? The tape shows that the orifice to the PTC fitting is 1/8th inch. Is it 1/8th inch line? I dont know if air line is identified by ID or OD. Thanks for your help.

Yes, 1/8" line. It's pretty thin-walled, so you may want to sheathe it for the whole run.

D.O.T. air line is measured by the outside diameter
