Well its just my luck that every place I could think of is out of stock of the fuel expansion tank things. Part number 533201511A (atleast on AutoHaus). It looks like the pictured one below.
So can I bypass this thing to get the car running? The entire fuel system has been cleaned so there is no dirt that will go into the fuel pumps if I bypass this. I know all it has inside of it are screens to prevent dirt going to the pumps or back into the tank.
