I replaced the sender with a 0-90 ohm unit so I could use the factory gauge with the aftermarket tank. Tested sender before install w/ DMM 0 empty, 90 full, and smooth transition between.
Did you compare the sender float arms for length? A shorter float arm would require more gas to raise the float and the reading wouldn't start soon enough.

"also you should ground the fuel plug-in at the fuse panel and check for empty in order to make sure the resistor on the fuel gauge is the correct resistance.
key on of course.
