The fuel pump on my 32 Model B has a "T" knob with spring behind it. What is this for? Is it a fuel shut-off, fuel pump drain or a way of regulating pressure, or what else? If it is an adjustable function, how is it adjusted.
From pictures of 4 cylinder pumps for sale, not all of them have this feature.
