Fuel system problem
I have 1979 z28. Not sure how long it was sitting before I bought it. But it drove fine for the first 4 months. Then It started have a hesitation and then would eventually die. I thought it was a vapor lock issue since it was in mid-summer. I changed out and insulated the fuel line from the fuel pump to the carb. This seemed to help for a few weeks. Then it got worse. It wasn't getting any fuel to the carb, so I replaced the fuel pump. And that fixed it for two days. Then I thought it might be a carb problem, thinking the float was getting stuck, so I re-built the carb. It didn't fix it. I am starting to wonder about the gas tank itself. Is there a way to find out if the tank has something in it that plugs the pump? I have this problem with a full tank or not. The books I have don't show a diagram on how the gas is drawn out of the tank.
