I put the tank in the below link in my 03 Mach 1 with a Cobra hat and Walbro pumps. I also put in a new vapor valve and new filler neck. When I go to add fuel it just will not go into the tank. I have tried undoing the evap lines and fuel lines and it still wont take the fuel. I'm stumped now. Anyone have any clue as to why this is happening?
