Heil Gasoline - Fuel Trailers For Sale

Heil gasoline-fuel trailers are built for petroleum delivery work where payload, safety systems, and unload efficiency matter every day. In this category, most buyers are looking at DOT 406, also written MC-406, aluminum tank trailers designed for hauling gasoline, diesel, ethanol blends, and other refined products. A common Heil configuration is the 9,200-gallon tandem axle trailer with an elliptical barrel, air ride suspension, aluminum wheels, and bottom-loading equipment. These trailers are widely used in convenience store, commercial fleet, cardlock, and regional fuel distribution service because they balance capacity with legal weight targets and maneuverability.

Compartment layout is one of the first decisions to get right. Heil fuel trailers in this class are commonly set up with four or five compartments, often in split sizes such as 3200-2300-1100-2600 or 2500-2100-1000-1500-2100. That matters if you are dropping multiple grades at one stop or running mixed gasoline and diesel routes. Buyers should also pay attention to bulkhead design, trough bottom or drain trough construction, internal drains, and product indicator hardware. A trough bottom petro tank can improve cleanout and product evacuation, which is important for operators managing frequent compartment turnover. Rear ladder versus front ladder placement, hose tube count, cabinet size, and stick tube location also affect day-to-day usability more than many first-time buyers expect.

On the compliance side, the major items are vapor recovery, overfill protection, emergency valve controls, and current test status. Many Heil petroleum trailers are equipped with Civacon overfill systems such as ROM II, ROM III, or ROMLink, along with top and bottom probes, internal vapor recovery, air-operated emergency valves, and EVO cabinets. ABS and roll stability systems from Bendix or WABCO are common on later units, and some newer trailers are spec'd with disc brakes and galvanized suspension hangers for lower maintenance. It is worth verifying annual inspection, leakage, pressure, and thickness-related requirements as applicable to your operation and jurisdiction, along with compatibility at the rack if you load through specific terminal systems.

Suspension and tire spec should match your lanes and service model. Heil fuel trailers are often found with Hendrickson Intraax tandem air ride suspensions, 49-inch settings, and either low-profile 445- or 455-series tires or 11R22.5 rubber depending on ride height and maintenance preference. Kingpin setting, axle track, landing gear, cabinet layout, and discharge hardware all affect how the trailer works with your tractor fleet and delivery sites. A lighter aluminum trailer can help maximize legal payload, but practical value comes from the full package: compartment sizing, brake package, vapor system design, rack compatibility, and the condition of the barrel, valves, and suspension components.
