摘要 |
A fuel tank system comprising a fuel tank (1); a device (3) with a fuel inlet (32) for receiving a fuel/water mix, and a water outlet in fluid communication with the fuel tank (1); and a filter (39) formed from a water-permeable material, such as graphene oxide, which enables water from the fuel/water mix to flow through the water-permeable material and the water outlet into the fuel tank, but substantially prevents liquid fuel in the fuel/water mix from doing so. The device may be a valve, pressure sensing line, or any other device in a fuel tank suffering the problem of water accumulation. |
