After i wired up the fuel gauge it bobbed up to 3/4 tank, about where it should be, then settled in at 1/4 tank. I put 5 gallons of gas in to fill the tank. It then showed 1/2 full. I drove it a couple time totaling about 8 miles then parked it and haven't touched it in the three weeks since. I had to move it out of my barn to get at something else and noticed the fuel gauge seems to read the correct full. Started it up a couple times and it goes up and down like it should. Hmmm... maybe I'm a genius.
Yes I know the cluster is crooked. It's on the list.
