Duke, you have a boyfriend?
Anyhow, I wouldn't suggest the braided upgrade. It costs a ton of cash and is really not necessary. If you have dirty tanks that can't be easily cleaned, I would use the braided line money to buy a fuel filter that spins on like an oil filter. 30-75 micron. Replace it more often than you need to and go have a great time with the boat.
As for the float, smack the bowl adjuster a few times with the plastic end of a screw driver. If that doesn't fix it follow Nordies recommendation.
