Overlooking something? Fuel Starvation

I had a fuel starvation problem over the summer. My car completely bogged on me twice when going down the quarter mile. We replaced the fuel tank and sending unit. The tank was very dirty and the sending unit was about shot. The sock was a mess. Unfortunatley I have yet to take it to the track to see if it helped but seems like it drives a little better.

It wouldn't hurt for me to check everything out on my car. I never have. I got new 3/8 fuel line that should be here today so everything from the tank to the carb will be new. Now the inside of the tank is a different issue.

Most of the time don't folks take the tank to the radiator shop and have them clean it?
