so was the issue the tiny fuel sock, or what?

 

What was the problem? I have the same issue

 

I mounted the pump about an inch lower and put the bigger oem sock on the pump.

 

I have the same problem but fuel tank level doesn't matter, happens all the time... Except in 1 and 2 gear. Throttle input doesn't seem to matter either.
I changed to a aero motive 340, id1000, and new ngk plugs, and new tune so idk what my problem is
