Ok so i figured out that there is a huge difference in the wiring of an electric fuel pump opposed to the manual float sensor. It was grounded to the HDX box, which it is not supposed to be. I went through most all of the pre programmed settings for sending units and the only one that registered to almost full was the manual one. I just topped it off and it reads just over 7/8 full.
I found out after cleaning it off that it is a Holly electric fuel pump and then researched it to have these ohm settings:

A Holley in-tank electric fuel pump typically has an ohms range of 73-10 ohms for Ford, Mercury, 144-429ci models, and 0-90 ohms for Chevy, GMC, Truck, 250-454ci models.

I will get it to the 0-90 range and see what happens
