Yea, I get that. I think I'm good there although I'll double check the breathers. The float reads ok. I can move the float up and down manually and the Guage reads the difference. The issue is when the sender is submerged in the fuel, the magnet in the float doesn't allow the float to float. It's too heavy. I put the float in the orange home depot bucket, as the bucket is where I emptied the fuel into, and the black plastic float without the magnet will slowly drift to the top. With the magnet, it dives down. I'm guessing bad float. I was wondering why there is a need for a hole above the float in the sender where a fuel line attaches to it. The manual is a tad vague at this point as to how and why, it just says where to attach the hoses. I tried a small piece of styrofoam underneath the float but it wasn't enough and I'm not sure if I want to use a larger piece. I guess I could use a larger piece or I'll have to get a fuel float kit but then I have to figure out how to install it as I'll have to make another hole in the tank. The challenge is going to be how to bolt it in as they are usually held in place with bolts and the holes are thereaded. Hmm, now that I think about it I could get a tap and die kit and thread the holes myself. Hmm. Man, this was almost easy. I just need the float to float lol.
