Before I write my regular post later, I figured I’d answer a reader question. Nahum Olin asks:
Why do you have the pit gun hose divided in two? I mean, there is the main hose, and then there is a short one, like the yellow one pictured on your article on the blog.
The small yellow hose connected to the gun is called a whip hose. The reason we use it to connect to the main air hose is for flexibility. Air hoses with 100PSI running through them can be stiff and having that whip hose and a quick connector in between allows the hose to move, turn, and flex. Without it, the main air hose would become a big twisted, tangled mess because we move so much. And twisted hoses are bad news because they can pull on the gun while you are trying to hit lugnuts and they become much easier to trip over. Thanks for the question Nahum!
