The fuel gauge has never shown completely full or completely empty and just shows 3/4 full down to 1/4 left. How do you troubleshoot such a thing?

Not sure what guage and sender you have.
My Gaffrig/Livorsi sender has 2 small screws for adjusting the Full and Empty settings. It takes some trial and error to get it set right

Baja you can do a quick test before pulling the floor. Most marine senders use 33 ohms to 240 ohms of resistance to determine fuel level. Check what the resistance is at full tank, and at empty. That will determine if it's your gauge or sender.

Finally got around to checking it. The bottom couple inches show an open circuit then starts at 190 and finished at about 70 full. Any thoughts on the best replacement.
