I have a problem starting my car when its sat for a day or more irregardless of outside temperature. I have stock quadrajet on a 71 400. Rebuilt carb, new pvc, good fuel pump, but I do have a repo gas tank that when I fill it i have ot go real slow or itll backflow out the fill tube, Ive wanderd if I need to be vented? or if the sending unit (new with tank) could be bad? when the car is started (usually by pouring fuel down the carb) and ran til its warm it can sit for hours and start fine, but if it sits for more than a day its the same business. Any ideas? I dont thinm its a fuel delivery problem because once it gets going its fine....
