still stalling

Posted recently that my 87 f350 stalls. The reply I was mostly centered around the tank pick up tubes and foot. So I filled the tank bled got the air out of the lines as far as the filter. If I press the bleeder nozzle above the filter it shoots out fuel no air. Looking at the injector pump the very top just off center left line is dripping a drop every 3 to 5 seconds and it's wet on the top of the line above the cylinder passenger side rear that is all I can see but there may be more. So the question is that enough to make her stall? She will idle fine just when I try to drive. About to order o rings to put in lines but what are the chances of not breaking the lines or they not being rusted so bad I have to buy all new ones?

It could be a problem with you check valve letting you lose prime. Mine had that problem and the tank selector valve was letting air in the system and the symptoms were the same. I am by no means a guru but I bypassed he tank selector valve and pu a check valve in between the lift pump and the filter head.....I hope it helps.
