Engineered as a direct replacement, it replaces both your failing 97-gallon fuel tank and your 20-gallon freshwater tank in a single, perfectly integrated unit. Built from heavy-duty, marine-grade aluminum, this tank eliminates the worry of old, corroded tanks and gives you the peace of mind to run offshore with confidence once again.

All tanks are made to order and the fabrication lead time is 1-2 workweeks. The finished tank pickup window is also 1-2 workweeks, so make sure you will be able to take delivery of your finished tank within that timeframe.  

  • Buy with confidence. Shortly after your payment clears you'll be sent via e-mail a complete set of detailed drawings for you to check all dimensions and fittings positions. If there's any difference from your old tank we can make any reasonable modifications to accommodate your needs. Fabrication of your new tank won't start until you send us your specs confirmation.

Shipping: Only freight to the 48 contiguous states. Contact us for extra-cost shipping options for HI and AK. Orders for international shipping from US-based carriers are welcome but contact us first to coordinate details.

Return Policy: No refunds are accepted, as all of our products are made to order. Our policy is strictly limited to the repair or replacement of qualifying defective or damaged goods. Please note that shipping costs are non-refundable. 

Due to this item's size and weight we can only ship it in an economical way via Less Than Truckload (LTL) consolidated land shipping, and only to the contiguous 48 States.

For shipping inquiries to AK, HI, PR, US-VI, and international shipping, please contact us first at sales@weldingworldinc.com.

All of the destinations above we can only serve as a Free Carrier (or FCA) modality, that requires the customer to contract and pay for their carrier service of choice. We can still ship the item, but only to a warehouse/receiving office within the 48-contiguous States.

In plain terms what this means is that if you want to ship your product to any non-contiguous US territory or internationally, you, the customer, has to provide us with the warehouse address of the carrier that serves your locality with an address within the contiguous 48-US States, as we do not ship overseas on our own.
