Where is the gas float located on a 1999 windstar van?
The fuel level sending unit (what you might be referring to as the "gas float") is located inside the fuel tank of a 1999 Ford Windstar. There isn't an external, accessible location. To access it, you'd need to drop the fuel tank. This is a significant job requiring special tools and safety precautions due to working with fuel. It's generally best left to a qualified mechanic.
