The Boyd Welding 100-gallon tank, product number 13015, is built from heavy-duty 3/16-inch (0.190") 5052 mill-finish aluminum with two internal baffles and AWS-certified welds, and every tank is pressure leak tested at 5–8 psi.

Choose from driver-side, center, or passenger-side pump pockets. This tank is sold only as a complete tank-and-pump unit. It's backed by a 2-year limited structural warranty from the date of purchase and ships in 1–2 weeks or less, with free LTL freight shipping to the lower 48 states.

Premium 3/16-Inch Aluminum Construction

Our 100-gallon tanks are the premium builds in our lineup. When you're carrying our largest fuel load, the extra material is worth it.

• The thickest aluminum we offer. These are the only tanks in our catalog built from 3/16-inch (0.190") 5052 aluminum. Every other tank we make uses 1/8-inch (0.125").
• Built for our biggest loads. At 100 gallons, these tanks carry more fuel than any other tank we sell, and their heavier walls are matched to that weight.
• More aluminum in every panel. The thicker walls make a heavier, more rugged tank, built for road vibration, moving fuel, and everyday work truck use.

Fuel and Use

This tank and all included components are compatible with both gasoline and diesel. Every tank is fully pressure tested and inspected following the 49 CFR 393.67 liquid fuel tank guidelines.

Truck Bed Fit

This is our largest standard tank, built for full-size truck beds where maximum capacity matters. Fit depends on your truck and bed, so measure before you order.

Measure your specific application before ordering. The tank body measures 49" L × 24" W × 22" H. Make sure the 49" × 26" mounting footprint fits your bed space and that the 24" overall height, including the fill cap, works for your setup. Allow for any mounting materials or supports, and for the pump and its connections in the position you choose. A full tank weighs roughly 745 lb with gasoline or 845 lb with diesel, so confirm that your truck and mounting can handle the load.

Before you order, see our Transfer Tank Install and Fitment Guide for fit checks, pump positions, and install steps.
