I have had this happen to me on an occasional basis. I fill up my front tank (I usually just use the front tank as the rear is tough to fill due to the utility bed) on my 87 f350 and when I start it up to leave it will surge and sometimes die. Normally it will start back up relatively easily, or I can keep it running by feathering the accelerator until the air bleeds out but today it did it to me again and I couldn't get it to start and I killed the batteries. after getting towed home it took quite a while to get it bled while charging the batteries all the while but I finally got it to start and now all seems normal. Anyone else have this happen to them or know what may cause it? It doesn't happen every time or even every other time, but it is a pain none the less. Other than that it starts fine all the time and I cant find any leaks in the fuel system. Thanks- Scott
