Installed this under the back seat of my crew cap truck in a couple hours. Every single piece needed for installation down to screws and zip ties was included in the package. I tied straight into my truck's fuel tank, and the supplied line was even the right size.The control is a little confusing at first, and the instructions are in grade-a Engrish, but assembly is pretty self-explanatory. I have a large RV trailer that we've had trouble heating ;I will be getting two more of these for it.
