What does the second stage do in the filter separator?

• A. Water droplets are stopped and pulled down by gravity on a Teflon coated screen
• B. It removes solids
• C. It heats the fuel
• D. It monitors flow

Answer: (A)

The second stage is focused on removing water from the fuel. Water droplets are denser than fuel, so they settle out as the fuel flows through this stage. A Teflon-coated screen catches and stops the droplets, causing them to coalesce and then be pulled downward by gravity to a drain or collection area. This keeps water out of the downstream filtration and helps prevent water-related issues in the engine or system. It’s not about solids removal, heating, or flow monitoring—that would be handled by other parts of the system.
