This configurator covers diesel fuel oil systems for single or multiple generators. You will be asked a series of questions that will help us configure the system. Recommended line sizes, pump, and strainer selections will be made. You will have the opportunity to make changes to these selections and see the system response in terms of pump discharge and suction pressures. When you are satisfied with the selections, the configurator will output a sample Preferred fuel oil specification for the system that is compliant with national fuel oil storage and handling codes. Projects in New York, Boston, or California are subject to more restrictive local codes and should be reviewed by a real fuel oil engineer, which you can reach by dialing Preferred's main number at 203-743-6741.
