Sounds like it might be a pump or something inside the tank, not getting fuel anymore. Anybody pull a tank on a c4 before?

Yeah figured it out. Pulled the sending unit out and the main fuel line from the pump came off, while I had it out went ahead and put a new pump and strainer in it. Figured I should since it was 30 years old. Thanks for the advice guys.!
