Fuel Guage
So my fuel gauge was reading Full when it was empty and way past full when it was full. I removed the fuel tank, ended up changing the sending unit for a new one. it seemed to work just fine. so I put it in the tank, put everything back together..... Ran out of gas at just below a half tank. I really dont want to remove the tank again. So if anyone knows what else the problem might be, please let me know.

No the metal wire holding the float. It will have to be bent. Hold it firmly at the sending unit itself and adjust it further down. Its easier to use a tape measure and measure the depth of your tank from the flange where the sending unit mounts. I usually set them where they are 1/2 to 1 inch from the bottom. I like to have a couple gallons in reserve. Our trucks won't run on fumes.

I took my fuel tank out, took my fuel sending unit out, kept it hooked up, put it at empty and it read a quarter tank. I put it at full and it read about a quarter over full. what the heck is going on??!!

Do you have the sending unit properly grounded? They work off of resistance and good grounding is necessary.

Its possible that the sending unit is defective or the wrong one. Doubtful but it could be your gauge as well. Or the voltage regulator for your instrument cluster could also be failing. Had the gauge ever worked correctly recently before changing the sending unit? Other gauges work ok?

the fuel gauge hasnt worked right for some time now. But just before I put the new sending unit in the fuel tank I hooked it up and made sure it worked right and it did empty was empty and full was full. Um, everything on the cluster works except the engine temp. that was going to be my next project.

So I went out and put it at full. It read about a quarter above full. I then slowly moved it down while someone else watched the Gauge, I got it all the way too what should have been half a tank before it even started to drop on the guage and I gave it plenty of time to move down before I got to what should have been half tank.
