Iam changing all the hoses under the hood since the car has been parked for several years. My question is the 3/4" hose from the top of the water pup to the heater core has a T in it with a 1/2" hose going to a fitting at the back of the intake manifold beside the distributor. Can I omit the T and use a brass plug in the intake or do I have to run the hose to it? I'm just trying to clean up the engine compartment a little bit.
