How To Understand The Holley 4180
|
Don't let the 4180's hoses and connections intimidate you. Each has an easy-to-understand purpose. Shown here is an evaporative emissions hose to the secondary fuel bowl, which keeps fuel vapors from escaping to the atmosphere. Below the secondary fuel bowl is the exhaust recirculation (EGR) valve. A sticking EGR valve will cause poor idle quality or stalling because manifold vacuum is what operates this valve during deceleration. The valve allows exhaust gasses to pass from the exhaust side back to the intake manifold. If the valve sticks in the "recirculation" position, it creates a vacuum leak and poor performance.
