How to Clean Off Stored Diesel Fuel

Diesel fuel is used in a variety of different vehicles and functions. The trucking industry relies heavily on diesel fuel for its industry since diesel has a higher energy output than regular gas and is used to power the trucks that make deliveries nationwide. Storing any kind of fuel for any length of time is challenging since the fuel can start to solidify and build up deposits that are detrimental to an engine and fuel system. Cleaning off stored diesel fuel before using it helps allow your vehicle or equipment to run at peak performance.

Instructions

- 1
  Insert the fuel pickup hose of a fuel polisher into the fill opening of the diesel tank and maneuver the hose so it goes all the way to the bottom. Most sludge will accumulate to the lowest portion of the tank, which is where you want the hose.
- 2
  Insert the discharge hose into the discharge bung of the tank if it has one. Any other tank opening will work since the discharge hose will be returning the fuel to the tank after it has been cleaned. You don't want to use the same opening as the pickup hose so the same fuel is not recycled over and over.

  Turn on the pump of the fuel polisher once the hoses are secure and leave it on for several hours, depending on the size of your fuel tank. Stay present the entire time so you can turn the pump off in the event of a mechanical problem. Keep the pump as far away from the tanks as possible to help prevent the chance of sparking or fire. Keep a fire extinguisher within reach.

  Add a biostat to your fuel supply in the last ten minutes of fuel cleaning by pouring it into the same opening as the fuel return hose. Biostat is a bio-friendly chemical that prevents algae and other microorganisms from growing inside fuel tanks.
