CW Fab Worx warrants each Product against defects in material and workmanship under normal use, beginning on the verified install date. Coverage requires online registration with proof of purchase and photos of the completed install. As of August 1, 2026, registration is mandatory — within 30 days of installation, and no later than 60 days from purchase.
- Tank body — seal-welded aluminum shell, seams, baffles, and welds: 2 years.
- Factory-installed components (fill-cap assembly, fittings, toolbox hardware) and finish: 1 year.
- Diesel fuel service only. Stated capacities are nominal — fill to a maximum of 80%.
Pumps (GPI EZ-8 / M-150) and other bought-in components carry their own manufacturer warranties. Full exclusions, claim steps, and transfer rules are in the complete terms.
