Do you think the tank got a lot of crap in it, it was replaced with a new one 2 yrs ago, as far as venting the fuel cap is as old as the car. This car has no vapor return system, I was waiting to replace the sending unit because if I need to do a vapor return line, I am hoping I can solve it without doing return line either way the tank gotta come out soon. The sending unit not registering the fuel level wouldn't cause this problem?
