Fuel care basics

Why does stored generator fuel need attention?+

Diesel can collect water and particles while it sits in a tank. Contamination can clog filters, encourage corrosion, and affect pumps and injectors. Regular fuel care helps address those risks before the generator is called on.

What does a fuel polishing system do?+

It circulates diesel from the tank through treatment equipment and returns it to the tank. Water separation and particle filtration help manage contamination in the stored fuel. Controls and treatment features vary by model.

What problems can it help prevent?+

Managing contamination can help reduce clogged filters, corrosion caused by water, and abrasive wear in fuel system components. Removing water also reduces conditions that support microbial growth. Fuel care helps reduce trouble caused by contaminated fuel, while regular generator maintenance remains essential.

Do I need to know which model I want?+

No. Tell Jorge what you know about your generator and fuel tank, and bring your questions. Tank size, fuel condition, operating duty, and installation details all help determine a suitable system.

Can a system connect to an existing fuel tank?+

We can discuss equipment for your existing tank during your consultation. The tank’s connections, layout, fuel condition, and electrical supply need to be reviewed before choosing equipment and planning installation.

Choosing equipment & getting started

How does AFFS help with installation?+

AFFS guides you from system selection through installation. We supply the equipment, connect you with a local installation vendor, and stay involved to help coordinate the next steps and answer equipment questions. The local vendor performs the installation.

Can I inquire from outside the United States?+

Yes. AFFS sells systems worldwide. Include your country and project location so Jorge can discuss the equipment configuration and local installation arrangements with you.

Does filtration replace generator or tank maintenance?+

Fuel filtration is one part of your maintenance program. Keep following the generator and fuel system manufacturers’ guidance for inspections, fuel sampling, servicing, and tank cleaning when needed. Filtration cannot restore fuel that has chemically degraded.

How much does a system cost?+

The right equipment and configuration depend on your tank and application. Request a consultation to compare options and discuss a quote for your project.

What should I have ready for a consultation?+

Your questions are enough to get started. If you have them, your tank capacity, project location, generator details, and a few photos can help Jorge understand the setup. You don’t need every technical detail before reaching out.
