Tech Tip: Keep Water Out of Your Fuel System

Be sure to check fuel filters for water after winter storage

It’s typical to get bouts of arctic cold in Chicagoland, so you’ll want to know about condensation issues that can occur with machines that get stored over the winter.

Water in a diesel fuel engine can cause major problems

Moisture can be an issue in fuel tanks during storage, and the emptier the tank the higher the possibility there is of having water in your fuel. This goes for your machine’s fuel tank, truck-mounted fuel tanks and stationary tanks.  Any water above the expected amount (a small amount of water will simply dissolve in the diesel fuel) can damage your fuel system and your engine as a whole, leading to expensive repairs down the line.

Now that you know water is a problem, how do you fight it?  Well, if you take one thing from this article, remember this: water always seeks the lowest point. If you give your fuel time to settle in the tank, it’ll separate and the water will head to the bottom. Then you can usually drain the water from a plug at the base of the tank. It’s also important to check seals for damage and the fuel filter to see if there’s water present.
