1/4" inside diameter. I recommend a self bleeder (attached permanently to the coolant expansion tank). Is fast, easy, and 100% fool proof. You can make your own, but note thread pattern in thermostat housing is BSPT, not NPT (28 TPI, not 27). Or simply buy a kit from one of the vendors. I think vendors may use 5/16" hose to match the existing bleed line.
