On-site storage allows for bulk purchasing to hedge against price volatility, eliminates equipment downtime spent at retail pumps, and ensures supply during regional shortages or delivery delays.

Start with your average daily fuel burn rate and how often you want to schedule refueling deliveries — most operations size their tank to cover one to two weeks of usage. From there, factor in whether the tank needs to be mobile (poly or aluminum transfer tanks) or fixed (steel above-ground or underground systems), plus any local storage limits from your fire marshal or state agency. Our fuel experts can run these numbers with you directly — Speak to a Fuel Expert .

Stackable systems (like Fluidall's Tote-A-Lube and Snyder's Cubetainers) allow facilities to store multiple grades of motor oil, hydraulic fluids, or DEF vertically in a single footprint. Paired with gravity feed kits and drip trays, they eliminate the need for electrical pumps and messy 55-gallon steel drums.

A UL-142 listing means the tank has been manufactured and tested to the Underwriters Laboratories standard for storing flammable and combustible liquids, ensuring a baseline level of safety and environmental compliance.

In most cases, yes. Local fire marshals or state environmental agencies typically require a permit for above-ground tanks over a certain capacity, and underground storage tanks (USTs) are subject to additional federal rules under 40 CFR 280. Requirements vary by state and municipality, so confirm with your local authority having jurisdiction (AHJ) before installation. Our team can help you understand federal baseline requirements like UL-142 and UL-2085 as a starting point. .

Above-ground storage tanks (ASTs) are generally simpler and less expensive to install and maintain, and are the more common choice for job sites, farms, and fleets. Underground storage tanks (USTs), like Newberry's Permatank® line, fall under stricter EPA regulations (40 CFR 280) covering leak detection and monitoring, but offer a smaller visual footprint. Most commercial and agricultural buyers choose AST unless space or aesthetics require otherwise.

Yes. UL-142, UL-2085, and EPA 40 CFR 279.22 are federal baseline standards, but many states and municipalities add requirements around setback distances, secondary containment, and permitting. Rules can also vary by what you're storing — diesel, gasoline, or used oil — and your total on-site capacity. Confirm specifics with your local fire marshal or state environmental agency; our team can help with the federal side as a starting point.

The 119-gallon mark is a key DOT threshold. Many of our portable diesel fuel storage tanks are sized at or below 119 gallons specifically to avoid triggering HAZMAT placarding for over-the-road transport. This threshold covers transporting fuel — separate rules govern how much you can store on-site.

Double-wall, or "bunded," tanks feature an inner primary tank and an outer secondary shell. This design is built to capture up to 110% of the primary tank's volume in the event of a leak, preventing environmental contamination.

No. Poly fuel tanks aren't rated for gasoline. Our poly fuel tanks are designed for diesel, DEF, and used motor oil (in our waste oil collection line) — gasoline requires a UL-142 steel tank or a DOT-approved aluminum transfer tank from manufacturers like ATI.

Yes, our Western Global and Newberry steel tanks are compatible with most standard biodiesel blends. We recommend confirming specific blend percentages with our technical team for long-term storage. .

Most agricultural operations use single- or double-wall steel skid tanks for bulk on-site storage, paired with a durable poly transfer unit like the Enduraplas Fuel Boss for field refueling.

Properly stored diesel typically lasts 6–12 months before degradation affects performance, though this varies with temperature, humidity, and any fuel additives used. Storing fuel in a sealed, vented tank away from direct sunlight and temperature swings — as our steel and poly tanks are designed to do — helps extend usable shelf life.

A fuel transfer tank is used to dispense fuel into other machinery, while an auxiliary tank is plumbed directly into your vehicle's factory fuel system to extend its driving range.

Both are double-wall steel tanks with lockable equipment cabinets for job site security. The TransCube is built for stackable, high-mobility transport between sites; the FuelCube is designed as a more permanent, higher-capacity fixed installation. Our team can help match the right configuration to your site's mobility needs.

No. Pre-configured gravity feed systems use the height of heavy-duty steel stands (24" or 36" legs) combined with brass or stainless steel spring-release valves to dispense high-viscosity fluids cleanly using natural gravity. However, larger Cubetainers (120–260 gallons) feature molded-in SS inserts to accept side-mount pump plates if an electric or pneumatic pump package is desired later.

Buying in bulk can let you lock in rates before anticipated price increases and reduces the labor cost of repeated trips to a retail pump. See our full analysis on the 2026 Diesel Fuel Price Forecast for more details.

Yes. Every tank needs a vent to prevent pressure buildup and vacuum issues during filling and dispensing. Our hardware line stocks both emergency and atmospheric vents.

Yes. These tanks are made from UV-stabilized polyethylene and feature weather-resistant, lockable manways, suitable for both indoor shop use and outdoor equipment yards.
