I'm having what appears to be a fuel flow issue, the lines are all new and the tank is very clean but I am having a fuel no fuel situation like something is clogging / restricting flow but not all the time. I've tried 3 pumps, 2 rebuilt and one new with the same results. I'm wondering if the in tank sock may be collapsing or some issue with the pickup tube. The tube looks to be soldered in the top of the tank, not sure how they got the sock on unless they did it before the tank was finish welded. Would like to hear from anyone who may have replaced or removed the pickup tube. I have a clear filter at the carb, clean as a whistle.

Thanks
