Rust looks harmless, but it’s not.
What starts as a little corrosion can turn into fuel leaks, environmental issues, expensive repairs, and most importantly, a generator you can’t rely on when the power goes out.
Last week, our team was at a condominium community just outside Boston replacing the rusted fuel tank beneath their 300 kW Caterpillar Inc. diesel generator.
At first glance, a rusty fuel tank doesn’t seem urgent. But ignore it long enough, and a small issue can quickly become a major problem.
Instead of waiting for that to happen, this property management team chose to proactively replace the aging tank with a new 164-gallon model from Zierke Built Manufacturing.
With the help of a crane, Roy, Billy, and Andy carefully:
• Disconnected the generator and removed the original tank
• Installed the new fuel tank
• Set the generator back in place
• Reconnected and tested the system
This is a great example of why planned maintenance matters.
Replacing a worn fuel tank before it fails helps eliminate emergency repairs, protects the property, and gives residents peace of mind knowing their backup power system is ready when they need it most.
The first few photos show the condition of the original tank, and the final images show the generator back in service.
If your generator is older and showing signs of rust or wear, our team would be happy to take a closer look.
