Boat Fuel Tank Fabrication in Naples, FL
Custom aluminum marine fuel tanks — built to your dimensions or as a direct replacement for a corroded or leaking tank, and pressure tested before it goes in the boat.
A corroded or leaking aluminum fuel tank is one of the most common problems on Southwest Florida boats — salt air and ethanol take their toll over the years. We fabricate custom aluminum boat fuel tanks from marine-grade aluminum, built to fit your existing space or to spec for a new install.
Every tank we build is pressure tested to check for leaks before it leaves the shop, so you know it holds tight before it goes in the boat. Bring us the old tank or send your dimensions, baffle layout, and fitting locations, and we build a direct replacement. This is work we do regularly — see our boat & marine welding and aluminum welding pages for the full range.
Need it handled at the marina, or want us to pull and refit the tank? Our mobile welding rig comes to you across Naples and Southwest Florida. Call (239) 438-5733 with your dimensions for a quote.
