So I went carbed and i have a sumped orginial tank the stock efi pickup hole is sealed and the only holes are the sump and the sending unit and the small round hole next to the orginial pickup hole. My qeustion is because the evap is gone there will be not venting for the tank so I do believe in need a vented cap for it if I am correct. So where do I get a vented cap to fit my 89 gt?
