A customer in Portsmouth, RI gave us the task of fabricating an aluminum fuel tank for the yachting industry. This tank is just one example of why, for over 20 years, Luther's Welding & Fabrications has been an industry leader in fabrication of marine fuel tanks.

This 125 gallon diesel fuel tank is used for a US Coast Guard 7.9 meter FRC Cutter. It was constructed of ¼" thick 5086 aluminum for its high strength, puncture resistance, and corrosion fighting oxide layer, all of which make it an excellent match for yachting.

Through SolidWorks for CAD design, our experienced engineers designed a tank that was 48.82" in length, 37.40" in width and 18.66" in height. To form the many complex components that make up the tank, our highly skilled operators used several of our extensive manufacturing capabilities including CNC plasma cutting and a press brake.

The tank had to be made with many elaborate features including an aluminum fill/vent box fitting, angle clips, aluminum gauge rings, flange and WEMA fuel gauge to ensure accurate fuel level readings. This was then carefully assembled and TIG welded by our ABS certified welders, followed by a comprehensive pressure test to ensure there are no leaks.

At Luther’s Welding & Fabrication, all of our products are constructed to meet our customers’ specifications including applicable CE, American Boat & Yacht Council and Coast Guard regulations. We take pride in our ability to manufacture our tanks and other marine hardware to accommodate the needs of our customers.
