Pick up intake

[Nick in Fayetteville]

On the 49-53 pick up truck intake, there is an extra vacuum port. It is located at or near the base of the carborator. What is it's purpose??????

It goes to the wiper motor.

I would think it is for the distributor or the windshield wiper motor, I don't have that year truck, just my guess!

That manifold is used on trucks that have vacuum brake boosters also. That is where the booster gets it's vacuum source.

Thanks 59ab. Your answer has to be the right one. I knew it wasn't for the wipers or distributor. I had that much figured out.

My 50 model engine has "one" vacuum port that I have seen. The one at the base of the carb, and it was hooked up to the wipers.

edit: aside from the obvious steel line, going to the distributor.

The one to the right is the larger brake booster port, the one on the left is for wipers
