Restore your vessel’s fuel system infrastructure with commercial-grade Blackfin 29 OEM replacement marine fuel tanks, engineered specifically to eliminate the vulnerabilities of aging, corroded factory cells. This complete heavy-duty system includes both the 162-gallon Aft belly tank and the 101-gallon Forward auxiliary tank, precision-fabricated by Welding World from extra-thick .190-gauge marine-grade 5052-H32 aluminum to vastly outperform standard factory specifications. Every tank features specialized V-bottom deadrise geometries tailored to your hull's precise stringer grid, internal slosh-control baffling to preserve stability in aggressive offshore conditions, and a thick, anti-corrosive TarGard epoxy coating to safeguard against saltwater pitting. Built in full compliance with ABYC, NMMA, and USCG standards, these tanks are delivered pressure-tested and complete with pre-installed mechanical plumbing layout components—including high-flow brass dual pickups and electronic sending units—ensuring a guaranteed 100% drop-in fit right out of the crate.

 

  • Guaranteed to Fit Your Blackfin
    Every tank is engineered using OEM drawings and/or reverse-engineered from an original unit to ensure a precise, 100% guaranteed fit.  

 

  • Fully Certified Manufacturing
    Our tanks are built by an NMMA-type certified manufacturer and produced in accordance with all ABYC standards.

 

  • USCG Compliant & Pressure Tested
    Each tank meets all USCG requirements and is individually pressure-tested in house. All federal regulations are followed throughout our manufacturing process to ensure maximum safety and reliability.

 

  • .190-Thickness 5052 H32 Aluminum Construction
    Built from premium marine-grade 5052 H32 aluminum at .190 thickness for exceptional strength and long-term durability.

 

  • Complete, Ready-to-Install System
    Each tank comes fully equipped with all required components, including the sender, fittings, and hardware.

 

  • Precision Hand-Welded Construction
    Every tank is hand-crafted using GTAW (TIG) welding, exceeding ASME and AWS D3.7:2004 standards for marine aluminum fabrication.                                                   

 

  • Sherwin-Williams® TarGard® Epoxy Coating
    Finished with Sherwin-Williams® TarGard® Epoxy to provide added protection against corrosion and harsh marine environments, extending the overall life of the tank.

 

  • KUS® (formerly WEMA USA®) Reed-Switch Fuel Level Sender
    Features a high-quality KUS® reed-switch sender with an NBR float, providing accurate and reliable fuel-level measurement.

 

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.  

 

IMPORTANT NOTE: The base price is for local pickup in our SW Miami Shop. Check options above for crating and shipping to the contiguous 48 States. All tanks are made to order and the fabrication lead time is 1-2 work weeks. The finished tank pickup window is also 1-2 work weeks, so make sure you will be able to take delivery of your finished tank within that timeframe.     

 

NOTE: Check your tank dimensions thoroughly! Once a tank is manufactured and/or shipped we can't be responsible for mismatches and refunds or returns won't be accepted. All sales are final!

 

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. 

 

Fabrication lead time (before shipping): 1-2 work weeks. 

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.
