fuel problem

ok i have a 350 with an edelbrock #1604 carb. i was driving it and all the sudden it starts to die. got it home changed everything in top of distributer. same problem. checked to see how good the gas was flowing. it was good. so i took off my fuel pressure regulator hooked fuel line straight to carb and it ran for about 20 min. then died. didn't bog down just died. i have been pulling my hair out for 3 week's over this. what do u think. should i try to rebuid the carb that was just rebuilt about 6 month's ago? i checked fuel filter and it had some kind of mesh stuff in it. it looked like carpet. lol but since then i have blew out the lines with an air hose. i really dont wanna drop the tank. any suggestions?

There is a sock/filter in the tank, they were famous for closing up when clogged. If you see debris in the inline filter pull the tank. 79 Camaro we assume?

yes its a 79 camaro. i guess i will be pulling the tank then. i didn't know about the mesh stuff in the tank and the tank is factory so i'm hopeing thats it. ty. will let u know how it turns out.

the sock was gone. so i took the carb apart and it was full of stuff. just rebuilt it not to long ago. so i got another rebuild kit and did that today. gonna put the carb back on tomorrow and see what happens.
