Hi, newb here.
My 4000 Quattro has been sitting for a few years, and I just started working on it. I got a fuel pump in but it seems like it's still not getting any fuel to the engine.
I found this part in the trunk.
Seems like some type of vacuum pump, which is why I'm thinking that there's no vacuum to get the fuel to the engine. Does anyone know where it goes, or where I can get a new one? I've been searching for anything related to it and came up with nothing.
Also, is there anything specific I should check for vacuum leaks?
Any expert opinions would be greatly appreciated. Thanks
