Hey, new to sight. Need help with a 69 bird. Fuel keeps heating and as a result I get air in the filter and car will eventually die. I can see the air build up cause it's a clear filter before the carb. Moved lines and now it takes about 45 minutes for the filter to go 1/2 empty. I'm positive it must be heat because I ran out of a gas can not the tank to assure there wasn't line blockage, new mechanical pump to make sure it wasn't diaphragm related. The engine itself is not overheating, it stays steady at about 195. It is all rubber from pump to carb, aluminum from tank to pump. Will going aluminum from pump as much as possible help to dissipate heat?? What about an electric fuel pump? But where do I wire in to?? Or a fuel line cooler? HELP!
