Fuel pressure dropping while driving and under acceleration to zero at idle runs 4 lb electric Blue

Thanks for all the replies. When I pulled the supply off of the sending unit it was flowing out free flowing full stream like you had to faucet turned on. I just can't believe that it could be this hard to figure out. People's been running electric fuel pumps for years. Without seeing it. It's hard to diagnose I know.... Are these holley blue fuel pumps not designed for a 3/8 sending unit and two filters. A 100 micron and a 40 micron. All new 3/8 fuel line to the regulator.... Again, I appreciate all of the replies. Just trying to get it through my thick head lol
