Had similar problems with my 70 f250 and ended up being that rust in the tank

would start up just find but because the suction from the fuel into the hoses would cause it to die after a few minutes. Same price to buy a new one as it is to get your old tank chemically cleaned. Once I swapped email out ran just fine

375

try making a external fuel tank out of a gas can put clean fuel in it remove the suction hose from the fuel pump and make sure it's all the way in start and run see if it still dies, i'm banking on clog needles or venturi blockage in carb,did you completely disassemble the carburator.GOOD LUCK
