FuelPro’s versatile 750 DEF trailers feature rugged, DOT-compliant construction, giving users the ability to refuel and service their remote equipment quickly and efficiently in the field.

The units boast 750 gallons of fuel capacity and 125 gallons of DEF capacity, the manufacturer reported. The chassis, which is made of 6-in. C-channel structural steel for longer service life, holds a tank built with 7-gauge steel that is double-seam welded for strength and durability.

“Each tank features internal fuel-surge baffles and cross bracing, a fuel-shutoff valve, a lockable vented fill cap, a tank pressure relief vent, and an at-a-glance fuel gauge,” the company stated in a release. “The DEF tank is constructed from 304-grade stainless steel, and includes a 50-micron stainless steel filter, and an at-a-glance stainless steel DEF gauge. The DEF system is purged and sealed per ISO 22241 standards.

“The FuelPro 750 DEF allows fast refueling of aggregate and mining equipment, heavy construction machinery, forestry equipment, and other equipment that is used in remote locations. “

A self-priming, industrial-grade pump rated at up to 25 gpm comes standard and runs on a deep cycle 12-volt marine battery. The fuel delivery system includes a 1-in. hose with an auto-trip nozzle. Hoses are available in 18-, 30-, and 50-ft. lengths, with an auto-retracting reel option available for quick and efficient refueling of loaders, skid steers, mowers, tractors, and more, FuelPro added.

Every trailer—all backed by a five-year tank warranty—is constructed using two torsion axles with EZ lube hubs and rated at 5,000 lbs. They also come with six- or eight-bolt steel or aluminum wheels, new ST235/80R16 radial tires, and electric drum brakes. Digital breakaway on both axles is standard, as are a seven-way RV plug connector and LED side and rear lighting.

“Safety and durability are designed into each FuelPro model, as heavy-duty safety chains and hooks, diamond plate rock guard fenders, reflective DOT tape, rollover railing, and a 7,000-lb. commercial jack all are standard equipment,” FuelPro added.
