Buying Guide

  • Capacity needs: Choose a tank that increases range without overburdening the vehicle’s balance and space requirements. SUVs and pickups benefit from mid to large capacities, while portable tanks are ideal for job sites.
  • Vehicle compatibility: Direct-fit tanks minimize fabrication. Always verify the tank’s labeling matches your make, model, and year.
  • Material and construction: Steel tanks tend to be durable but heavier; high-density polyethylene tanks resist corrosion and are lighter. Consider climate exposure and UV resistance for portable tanks.
  • Fuel compatibility and filtration: Some models include dual-filter systems to improve diesel purity. If you expect contaminated fuel, prioritize filtration features.
  • Installation considerations: Check for clearance around steps, airbags, and electrical components. Mid-ship tanks generally avoid drivetrain interference, but verify undercarriage clearance.
  • Security features: Lockable lids help prevent tampering on portable tanks or in fleet scenarios.
