Keeping heavy equipment fueled in the field — on drilling pads, along pipeline ROW, on remote construction sites — is a logistical challenge every fleet manager knows. STI fuel service truck bodies are purpose-built for exactly that job: safe, efficient on-site fuel delivery and storage for diesel-powered fleets across Texas and Louisiana.

At Star Truck Equipment in Wharton, TX, we install STI fuel service bodies on chassis cabs for oilfield operators, construction companies, and agricultural fleets throughout South Texas and the Gulf Coast.

What Is an STI Fuel Service Body?

An STI fuel service body converts a heavy-duty chassis cab into a mobile fuel delivery and fluid management station. Key features typically include:

  • Primary diesel fuel tank — 100- to 500-gallon capacity depending on configuration and chassis payload
  • DEF (Diesel Exhaust Fluid) tank — Dedicated DEF storage and metered dispense for Tier 4 equipment compliance
  • Fuel transfer pump and meter — Accurate metering for inventory tracking and billing
  • Fuel dispensing hose reel — Self-retracting reel for clean, efficient fuel delivery
  • Auxiliary fluid tanks — Engine oil, hydraulic fluid, and water storage for comprehensive field service
  • Grounding cable and static reel — Required safety equipment for fuel operations
  • Lockable steel compartments — Secure storage for filters, tools, and safety equipment
  • DOT compliance package — Proper venting, bonding, and placarding for legal fuel transport

STI Fuel Service Body Models

  • STI Fuel/Lube Combo Body — The most popular configuration for oilfield and construction fleets. Combines diesel fuel delivery (150–300 gallon) with a full lube fluid management system in a single truck. F-550 or Ram 5500 chassis base.
  • STI Fuel-Only Service Body — Maximizes fuel tank capacity (300–500 gallon) for operations that have separate lube trucks. Larger tank capacity requires F-600 or medium-duty chassis for proper payload margin.
  • STI DEF + Fuel Body — Purpose-built for Tier 4 equipment-heavy fleets. Includes dedicated DEF tank, metered DEF dispense, and primary diesel — all DOT-compliant.
  • STI Crane + Fuel Combo — For operations that need fuel delivery AND lift capability in a single truck. Tiger Crane integration available on F-600 or medium-duty base.

Industries We Serve With STI Fuel Trucks

  • Oilfield operators (Eagle Ford, Permian, Gulf Coast) — Drilling pads, production facilities, and tank battery locations where fuel delivery to generators, pumps, and service equipment is a daily necessity
  • Pipeline construction companies — ROW crews running HDD rigs, trenchers, compactors, and excavators need mobile fuel service to keep pace with production
  • Construction fleet managers — On-site fuel trucks eliminate the need to transport equipment to a fuel depot, saving hours every day on large job sites
  • Agricultural operations — During planting and harvest, field fuel trucks keep tractors, combines, and irrigation pumps running without interruption
  • Utility and municipality fleets — Public works crews and utility line crews use fuel service trucks for on-site fueling of generators, aerial lifts, and maintenance equipment

DOT Compliance for Fuel Trucks in Texas

STI fuel service bodies come with the safety and compliance equipment required for legal fuel transport under TXDOT and federal DOT regulations. This includes proper tank venting, bonding cables, placarding, and fill-point locations. We can walk you through the specific requirements for your application and payload before we build your truck.
