Still trying to trouble shoot my boost problem...



So the pressure tank is the black plastic tank on top of the engine in front of the intake manifold right? And the vacuum tank is the black plastic tank on the front of the engine between the alternator and power steering pump right?



Some things I have read say that BOTH the pressure tank and vacuum tank should have one way valves. My pressure tank has two lines going into it and I replaced the existing one way valve when I did my silicon vaccuum line job. The vaccuum tank appears to have only one line going into it at the top and no one way valve. Is this correct? Should I add a one way valve to the line going into the top of the vaccuum tank?



Thanks,



John

 

Here's a link to the color hose diagram:

You are right about the locations of the pressure and vaccum chambers. It doesn't look like there is a check valve on the vaccum
