Instructions are diabolical, blurred small numbers, mostly explains where to install it in your car, truck or van. Pipe work is all guess work. Like how it says, easily transferable, you have to bolt it to something and make a hole for the exhaust, my combi must be easy to transfer too. You could put the pipe out the window or door, the pipe is approx 2ft long and doesn't bend enough to leave clearance to bolt to floor, 50mm timber would work. Fuel cap looks big enough to poor from a Jerry can.
