Can you post the log and tune? It will be easier to try and figure out.

I took apart the fuel pickup in the tank. It was quite a ways from the bottom. I was able to bend it down. My car has very little rake which doesn’t help the situation. I filled it up to the cap and with the pickup tube mod it runs great. I may put a Holley hydramat on if if I keep having issues.

Glad you got it figured out!
