Fuel System Specs | Preferred Utilities Mfg

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. Some areas of the U.S. have more restrictive local fuel handling codes. For projects in New York City, contact John Haber at jfhaber@acs-ny.com. He will assist with a design and specification compliant with the latest NYC codes and practices. You can always call and talk to an engineer experienced with fuel handling systems at Preferred's main number 203-743-6741.

How many generators are in this system?

Are day tanks required for the generators?

YES NO

Do you want return pumps on your day tanks?

Return pumps are required for most systems with aboveground main storage tanks. They are recommended for systems with underground storage tanks too. Return pumps make the fuel oil system easier to commission, and easier for the owner to periodically test.

YES NO

How many main storage tanks are in this system?

Total capacity of all the main storage tanks?

Is the main fuel oil storage aboveground?

YES NO

Specify fire-rated (U.L. 2085) main tank(s)?

YES NO

Specify double wall containment pipe?

Aboveground pipe usually does not need to be double wall containment pipe, but it is often specified for additional leak prevention and detection. Indoor fuel piping is usually specified as double wall pipe.

YES NO

What is the location of the fill boxes?

What motor voltage is available to the system?

Specify an automatic fuel filtration system?

Automatic fuel oil filtration is recommended for emergency diesel generators and dual-fuel boilers that do not fire on oil enough each month to keep their fuel fresh.

YES NO
