Gravity Fuel System
Calculate Your SOLO Savings
See exactly how much you'll save by switching to the Gravity SOLO model — no technician required, no inflated day rates.
Gravity Fuel Systems delivers automated, gravity-fed fuel delivery for frac operations without pumps, motors, or dedicated continuous on-site technician support.
Built for demanding oilfield operations, Gravity helps operators reduce fuel-system cost, reduce mechanical failure points, support continuous hot-fueling, and improve safety with low-pressure fuel delivery.
Gravity uses a patented gravity-fed delivery system that reduces dependence on pump-driven fuel movement. That single design difference creates advantages across cost, reliability, safety, and operating simplicity.
Every operation is different. That's why we built this calculator around your actual usage. Enter your numbers below for a real-world savings estimate based on SOLO's proven delivery rates and fuel efficiency.

Gravity uses a patented gravity-fed delivery system that reduces dependence on pump-driven fuel movement. That single design difference creates advantages across cost, reliability, safety, and operating simplicity.
Conventional AFS systems often rely on pumps, motors, higher mechanical complexity, and more service dependency. Gravity simplifies the fueling system so operators can keep frac equipment fueled with fewer moving parts, fewer service interruptions, and lower operating cost.
Key Advantages
In demanding frac operations, a fuel system failure can create downtime, service disruption, and unnecessary field complexity. In remote environments, the impact can be even greater because mechanical failure is harder to resolve quickly.
Gravity reduces mechanical complexity by eliminating pumps and motors from fuel delivery. Fewer moving parts mean fewer failure points, lower maintenance exposure, and less dependence on emergency technical intervention.
Key Benefits
Gravity’s SOLO model helps remove one of the largest recurring costs in conventional AFS operations: the dedicated on-site technician. With a lower day rate and a simpler system architecture, Gravity helps operators reduce monthly fueling costs while maintaining consistent delivery across active frac operations.
For U.S. operators focused on pad economics, Gravity can help reduce AFS cost, simplify field support, and improve margin across single-well pads, multi-well operations, and Simulfrac programs.
Key Benefits
Simulfrac operations are growing across major U.S. plays and other high-demand frac environments. Many AFS systems require two units to support the job. Gravity is built to support high-demand Simulfrac and Dual Frac fueling with a single unit, helping operators reduce equipment count, lower cost, simplify location layout, and improve pad economics.
Key Benefits
Gravity uses a patented delivery valve that responds to tank pressure and helps maintain fuel levels automatically. The system supports automatic fuel delivery without relying on pumps, motors, or complex electronics for fuel movement.
For cost-focused operators, that means less field support burden. For remote operators, that means fewer mechanical components that can fail. For every market, it means a simpler automatic fuel system built for consistent frac equipment fueling.
Key Benefits
Gravity supports continuous hot-fueling of frac pumps and associated equipment while operations are running. The system is designed to help maintain fuel supply during active pumping operations without forcing unnecessary interruptions for refueling.
That helps operators keep equipment running, reduce refueling-related downtime, and support continuous frac activity across demanding field conditions.
Key Benefits
Gravity delivers fuel at approximately 7 PSI, which is well below the pressure levels that can create hose spray and turbocharger fire risk in conventional systems. The double-wall flame shield tank and integrated spill containment reinforce a safety-first system architecture.
Gravity is not a pump-based AFS with safety features added later. It is a different fueling system built around low-pressure, gravity-fed delivery.
Key Benefits
Gravity aligns with the way operators and procurement teams define automatic fuel system requirements for fracturing operations. The system supports automated fuel delivery, gravity-fed flow, continuous hot-fueling, fuel storage, field installation, commissioning, maintenance support, and monthly rental operation.
This makes Gravity easier for procurement, operations, and engineering teams to evaluate against automatic fuel system RFQ requirements.
Gravity is designed to support the full scope of field deployment, from delivery and installation to commissioning, maintenance, and demobilization. For remote operations, this matters because the fueling system must be more than equipment on location. It must be a reliable rental solution that can be installed, commissioned, maintained, and supported for the duration of fracturing activity.
