Fuel Gauge Issue

Ive been having problems with my fuel pumps/ levels since i got the truck...fuel level gauge has never read properly... so i cut my losses and got new fuel pump units front and back....

they pump like a dream BUT.... on my gauges on both tanks... when the float is in it full position the gauge reads bang on E.. and when i move the floats to empty... it goes up the the 3/4 mark..... to me it seems like a polarity issue somewhere?? but im no expert auto electrician....

any help would be excellent!!

BTW its a 1988 F250 4x4 5.0

Check the connectors....The one on the tank, the one beside the tank-on the frame rail, and the ground (On the 1992+ trucks, its on the radiator support, beside the D/S headlight)...
