I hope All of my booster pumps take in fuel from as close to the bottom of the tanks as possible just as my car does.
Some tanks even have sumps to ensure a bottom take-up.
Squash plate high pressure fuel pumps hate water with a vengeance. They must have continuing lubricity.
Special fuel additives are generally successful at absorbing small amounts of water in solution with the fuel and combat the formation of ice crystals if the fuel should reach very low temperatures. Fuel in the tanks is a large reservoir of heat and rarely is extremely low fuel temperature a problem even within integral tanks.
Fuel filters trap ice crytals and some can seperate out water.
