Thus fueling (eg from a boat) is a breeze. This pump saves any spills with hoppers etc. Without electricity quickly pumping large quantities - always works great. In addition, specifically the pump this trader from a while quite rigid, but extremely high-quality material. Fuel drips from it almost completely, and the tube is almost completely dry after pulling from the tank / canister miraculously !! You get extremely rare "gasoline finger". We recommend!
