Day Tank

A fuel management system comprising a day tank configured to receive fuel from a chassis fuel tank and to receive return fuel from a generator; a fuel level sensor configured to generate a fuel-level signal indicative of an amount of fuel within the day tank; a fuel pump transfers fuel from the chassis fuel tank to the day tank; a pressure switch generates a pressure signal indicative of an over-pressure condition within the day tank; a fuel venting assembly configured to vent air and vapor from the day tank; a fuel strainer; a generator fuel pump, a fuel filter/water separator, a control circuit actuates the fuel pump when the amount of fuel in the day tank is below a first threshold, deactivate the fuel pump when the amount of fuel in the day tank is above a second threshold, and deactivate the fuel pump upon detection of the over-pressure condition.
