Thanks beltfed, Sounds like my next step.
I wired everything up like I believe it should be. When I first turned the key the needle bopped up to 3/4 tank. About where I thought it should be. Then it moved around a bit and settled on 1/4 tank. I put five gallons if gas in it to fill the tank. The needle did move up to just about 1/2 tank.
Sooo...what's all that mean? Whenever I have something that "kinda works" I usually have a questionable ground somewhere, but I'm by no means knowledgeable with anything electrical.
