I just purchased a 2005 Fleetwood Rv with a 300 Cat engine on a Freightliner chassie . Where might the fuel filter water drain be located on the engine or soeplace else?
Most engines have two fuel filters. Primary and Secondary. The primary filter is the first one the fuel sees coming from the fuel tank and it often is equiped with a drain valve and a sensor that tells you there is water to be drained.
