Tell me whats wrong with this pic and how to fix it

It is a check valve which allows the motor to apply vacuum in the booster and store it. If there is tape on the valve it is probably damaged and should be replaced. any mopar with power brakes will work its only a one way valve. Make sure all of your vacuum hoses are plugged as this could also cause a booster operation problem. I see one in the photo that is open. I have a valve if needed you pay the ride. $5 paypal [email protected]
