FUEL SYSTEM SERVICES
Fuel Polishing • Tank Cleaning • Fuel Quality Testing • Contamination Removal
At CoreUptime Power Systems, we understand that fuel is the lifeblood of every standby generator. Even the most reliable engine and the most advanced control system will fail if the fuel feeding it is contaminated, degraded, or unstable.
Our comprehensive fuel system services are engineered to ensure your generator starts when you need it most — whether you're supporting a data center, hospital, industrial facility, municipality, telecom site, or commercial operation.
Your uptime depends on the quality of your fuel.
We make sure it stays clean, stable, and ready.
Why Fuel Maintenance Matters
Diesel fuel begins degrading in as little as 6 months. Water contamination, microbial growth, sludge buildup, and particulate matter can clog filters, damage injectors, corrode tanks, and choke engines during an emergency event.
Common failures caused by bad fuel include:
-
Engine won't start
-
Engine bogging or shutdown during transfer
-
Dark or cloudy fuel
-
Excessive filter clogging
-
Smoking or rough operation
-
Water contamination in the tank
-
Injector and pump damage
-
ATS failure due to generator stall
-
Complete outage during an emergency
Regular fuel maintenance isn't optional — it’s critical.
Our Fuel System Services
1. Fuel Polishing (Multi-Stage Filtration)
Our advanced polishing process restores fuel quality by removing:
-
Water
-
Microbial growth (algae)
-
Sludge and sediment
-
Oxidation byproducts
-
Contaminants
-
Particulates
We recirculate and clean the entire fuel volume, not just the surface layer, ensuring your generator receives only clean, stable, reliable diesel.
Recommended Frequency: Every 6–12 months (depends on tank size, climate, and generator load profile)
2. Tank Cleaning & Internal Inspection
Fuel polishing addresses the fuel — tank cleaning addresses the cause.
We perform:
-
Internal tank inspection
-
Removal of sludge and debris
-
Water extraction
-
Tank bottom cleaning
-
Corrosion assessment
-
Fuel level sensor inspection
This service prevents recurring contamination and extends the life of your tank.
3. Water & Sludge Removal
Standing water in diesel tanks is the #1 cause of microbial growth (“diesel algae”).
We use specialized equipment to safely remove:
-
Free water
-
Emulsified water
-
Sludge
-
Debris
-
Microbial biomass
This ensures fuel stays stable and the generator starts reliably.
4. Fuel Quality Testing & Analysis
We provide lab-grade testing and reporting for:
-
Water contamination
-
Microbial growth
-
Particulate contamination
-
Cetane degradation
-
Sulfur level compliance
-
Fuel clarity & color
-
ASTM fuel stability
This data-driven approach allows you to plan maintenance and budget for long-term reliability.
5. Filter Changes & Fuel System Component Inspection
During service, we inspect:
-
Primary & secondary filters
-
Lines & fittings
-
Fuel pumps
-
Day tanks
-
Transfer pumps
-
Fuel heaters
-
Water separators
We replace filters using OEM-quality components to maintain reliability under load.
6. Fuel Recirculation System Installation (Optional)
For high-criticality sites (hospitals, data centers, industrial), we can install continuous fuel recirculation systems to keep tanks in optimal condition year-round.
This is often paired with:
-
Remote fuel monitoring
-
Temperature tracking
-
Water detection sensors
-
Secondary containment systems
