If your work environment demands ruggedness, reliability, and effective fuel logistics, your choice of a quality fuel tank counts. FRDM Fabs‘ premium Fuel Tanks Collection offers a line of heavy-duty, high-capacity tanks specifically made to fuel heavy equipment, fleet vehicles, and backcountry operations. In this, we walk you through what makes the tanks superior, how to choose the best for your setup, and how to ensure safe, effective fueling operations.
Why a Good Fuel Tank Purchase is Necessary
Fuel tanks do more than merely store gas or diesel. A quality tank increases work efficiency and saves operating costs by:
- Saving fuel loss and evaporation
- Proving consistent fuel pressure to engines
- Keeping structural integrity intact in the event of stress, movement, or tough terrain
- Saving downtime by being easy to fill, maintain, and monitor
- Withstanding corrosion, impact, and extreme weather conditions
- FRDM Fabs’ tanks are built to do exactly that—without compromise.
Types of Fuel Tanks Offered
Here are some of the common fuel tank styles you’ll find in our collection, along with their ideal applications:
1. Underbody/Chassis Fuel Tanks
Compact, rugged bins mounted on the underside of trucks — popular for service bodies, flatbeds, and mobile units.
- Flatbed or Deck-Mount Tanks
Large, above-bed tanks designed for heavy equipment haulers, work trucks, or trailers carrying machinery.
- Portable Diesel Fuel Boxes
Secure, mobile tanks for off-site areas, construction sites, or emergency fueling where normal stations are not convenient.
- Dual-Compartment Tanks
Allows you to store two different fuels (like diesel and DEF) or divided reserves, ideal for long-haul operations with varying fuel needs.
Each tank is built of heavy steel or corrosion-resistant metals, with heavy-duty welding, sealed fittings, and designed to hook up with your existing fuel lines.
How to Select the Right Fuel Tank for Your Use
It’s not guesswork selecting the right tank — it involves measuring your workflow, terrain, and fuel needs:
Capacity vs. Weight
Additional capacity equals more fuel, but also more weight. Opt for a size that maximizes range against payload limits.
Mounting Location
Will the tank be under the bed, across the deck, or on a trailer? Allow sufficient clearance, stability, and hose routing.
Material & Construction
Wall thickness, baffles (to decrease slosh), weld quality, and corrosion resistance all have an impact on longevity.
Fuel Delivery Style
Select gravity feed, pump-fed, or suction systems; see to it your tank supports your existing fuel delivery style.
Access & Fittings
Drain plugs, gauge locations, simple fill ports, and inspection hatches simplify operation and maintenance.
Regulatory Compliance
For government or commercial application, ensure your tank is EPA, DOT, or locally approved — FRDM Fabs will provide documentation upon request.
Installation & Setup Tips
Your tank is no more dependable than its installation. Use the following tips to achieve best performance:
- Employ the use of proper mounts and hardware to avoid points of stress.
- Fuel lines align away from heat sources, sharp edges, and areas of movement.
- Ground your tank soundly to reduce static risk.
- Vent properly to prevent pressure buildup or vapor lock.
- Pressure test the system prior to complete fueling.
- Label with fuel type and safety info according to local code.
FRDM Fabs assists customers with mounting kits, mounting options, and technical support to ensure a clean, assembly-ready installation.
Maintenance & Longevity Best Practices
To safeguard your fuel tank investment and avoid operational problems:
- Inspect regularly for leaks, corrosion, or weld damage.
- Drain water and condensation from bottom sumps or drains.
- Clean strainers, fuel filters, and pumps regularly.
- Repair chipped paint or coating in a timely fashion to prevent rusting.
- Monitor and re-calibrate fuel gauges as required.
Maintenance makes fuel systems reliable — your work isn’t done just because the weather or conditions become worse.
