Using a 9046F Tank Sweeper from IPA to polish/clean diesel fuel from an off highway fleet truck. The product can be found on their website at http://www.ipatools.com/products/inde... . Focused on my favorite features which is the flow through brush. This system can also be used for transferring fuel, hydraulic/motor oils and transmission fluid. They also come with filters for removing emulsified water from oil. As mentioned in the video, the stock wands are long but they are made long enough for large in ground type tanks. You can cut them shorter or even adapter your own ends.
