Buying Guide: 90-Gallon Tank Considerations

  • Material choice: Steel tanks offer maximum rigidity and impact resistance, but are heavier. Aluminum tanks save weight and resist corrosion, which can improve service life in harsh environments.
  • Mounting and fit: Check your truck bed or saddle box dimensions, center-of-gravity, and mounting hardware compatibility. L-shape designs fit certain box configurations better than straight tanks.
  • Integrated features: Toolbox integration, vented caps, lockable lids, and built-in pumps affect usability and security on job sites.
  • Fuel transfer performance: Higher GPM pumps reduce fueling time but may require more power or wiring. Consider hose length and nozzle type for field operations.
  • Safety: Look for baffles, venting, spill containment, and secure locking mechanisms. Proper installation reduces slosh and accidental spills.
  • Maintenance and care: Aluminum tanks resist rust but need regular cleaning and inspection. Steel tanks require corrosion protection and maintenance of seals and caps.

Frequently Asked Questions

  • What is a 90-gallon diesel tank best used for?

    It is best for extending fuel range on work trucks, construction sites, or long-haul utilities where frequent refueling is impractical.

  • Do aluminum tanks rust?

    No, aluminum resists rust better than steel, but aluminum can corrode in certain environments if exposed to salt or chemicals; proper coatings help longevity.

  • Is a toolbox-integrated tank worth it?

    Yes for on-site versatility, reducing the need to carry separate storage and fuel containers, especially in mobile service scenarios.

  • What should I consider about pump flow rate?

    A higher GPM pump speeds up refueling but may require more power and a robust wiring setup; choose based on your daily fueling volume.

  • How do I ensure a proper fit in my truck?

    Measure the bed or cargo area, confirm mounting points, and compare with tank dimensions and box clearance to avoid interference.
