The soup bowl has no lines that go into it. It just has the two pin holes in it. Again, the vent lines do NOT go into the soup bowl. If you coat the inside of the tank the only problem you may have is plugging up the two pin holes and then the soup bowl will do absolutely nothing other than take up space. Also to answer your other question, the two vent lines get tee'd together and then connected to the filler neck, the third one used to go toward the front of the car and connect to the charcoal canister. We should not re-visit this, it has been discussed many times on the forum. We have to find one of the old threads and just link to it - found a good one read the whole thread. Most of them are associated with gas smell inside the cabin.If someone can help me understand the expansion bowl and the vent fittings at the rear driver side of the tank.
From the two external vent fittings, is there an internal hose/tube that connects to the vent holes on the expansion bowl, or are the expansion bowl's two vent holes open to the tank?
