Moeller has designed a variety of custom application fuel tanks for many different customers. All Moeller's permanent tanks are ABYC and NMMA compliant. ,Tanks typically ship directly from the manufacturer depending on the size. Many tanks are custom fabricated and may have a 2-3 week leadtime. Please check with our sales department to check stock. Also fuel tanks are considered oversize therefore at time of transit we may need to adjust the shipping charges to reflect the actual cost to ship.
