1986-1987 Buick Turbo Regal -
REPLACEMENT BOOST LINE VACUUM T
The wastegate solenoid, turbocharger and wastegate actuator are connected by three vacuum hoses and a grey plastic "Y" fitting.
This replacement Y connector is similar in size with the correct orifice in the one outlet which match the original vacuum T. When you install this new Y, you will need to insert the same hose into the metal orifice opening as the original T.
Inside the one side of the connector "Y" fitting there is a metal orifice, which allows only a small amount of vacuum to pass through. If the "Y" or surrounding vacuum hoses are damaged or cracked, you can have an overboost condition.
You should also check the three hoses for possible cracks due to heat or swelling at the ends. This could cause engine damage from leaning out the air/fuel mixture.

Another excellent replace item for the engine.
