Maximize your offshore endurance and eliminate fuel system vulnerability with custom-engineered Jupiter 31 Cuddy Port and Starboard OEM replacement marine fuel tanks (105 gallons each). Built to permanently resolve the corrosion and stress issues common to aging original saddle cells, this matching pair is precision-fabricated by Welding World from heavy-gauge .250-thickness marine-grade 5052-H32 aluminum—delivering twice the structural strength of standard factory builds. Custom-contoured to match the exact hull deadrise geometries of your Jupiter 31's port and starboard outboard stringer bays, these cells feature internal anti-slosh baffling, heavy-duty mounting tabs, and complete encapsulation in a thick black TarGard epoxy coating to resist saltwater pitting in tight bilge environments. Built in accordance with strict USCG, ABYC, and NMMA standards and pressure-tested in-house, these matching 105-gallon tanks ship fully equipped with high-flow brass pickups, electronic sending units, and heavy-duty fill and vent fittings, guaranteeing a 100% direct drop-in fit for a seamless refit.

 

  • Guaranteed to Fit Your Jupiter
    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

  • .250-Thickness 5052 H32 Aluminum Construction
    Built from premium marine-grade 5052 H32 aluminum at .250 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.

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.
