| I am definitely not familiar with z32's fuel setup but I am familiar with the Ferrari 360's Long story short, one of the check valves on the 360's evap system was faulty, resulting huge vacuum in the fuel tanks ( sourced from the intake plenum). The result is a $6000 aluminum fuel tank collapse because of its material. And this car has 2 fuel tanks. Now, if somebody can draw a diagram as where's the Z32's fuel vapor goes to and what valves or hoses are between the charcoal canister and fuel tank, that'll be greatly appreciated! my Z's tank's always got a vacuum since I always hear a "pzzzz" when I was opening the gas cap! :Also since I installed the walbro fuel pump, when I take off my fuel cap to fill fuel it no longer has that vacuum sound to it.
:Which makes me wonder if that's a byproduct of installing this type of pump or if maybe some of my fuel lines aren't tight.
:Thoughts?
