My dad uses a '77 peterbilt at work, at a Gerogia Pacific, as a yard dog to move chip trailers around.
He had a question, Theres a hose that runs from under the cab to the intake manifold creating like a T splitter. From the T, theres a hard line running down to the fuel pump. So basically a rubber hose coming from under the truck, to the intake manifold, then a hard line from there to the fuel pump. He was just wondering what it is. He's wondering why it connects to the intake.
He said the truck was running rough and very crappy, then one of his buddies took vice grips and clamped the rubber hose shut and the truck runs perfect now.
Any help would be GREATLY appreciated.
