In one embodiment, a water drainage system for a fuel system comprises a fuel tank, a fuel-water separator in fluid communication with the fuel tank, and a purge tank in fluid communication with the fuel-water separator and the fuel tank, the purge tank separate from the fuel tank. The water drainage system further includes a fuel property sensor for detecting a presence of water and a purge line in fluid communication with the purge tank for removing fluid from the purge tank, a flow of the fluid from the purge tank controlled by a check valve."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for water drainage in fuel system","description":"Methods and systems are provided for operating a vehicle including an engine and a fuel system.
