68 longbed 5.3/4l60e

[tallic68]

The original tank did not have a vent. I'm guessing the new one dosen't need one either for now. But once I get the 5.3 in and the external fuel pump hooked up, will I need one then? I have 3/8 hard line from the tank along the frame to below the drivers door. I was planning on mounting the pump there and running braided line from the pump to the fuel rail with standard 3/8 rubber line as a return.
