Power long-range offshore runs and restore tournament-level dependability with this Donzi 35ZF Main (186 gal) & Aux (75 gal) 2003 OEM replacement fuel tank package. Precision-engineered in Miami, FL by Welding World Inc., this heavy-duty dual-tank system is custom-fabricated from offshore-grade .190" marine 5052-H32 aluminum to comfortably endure extreme hull flexing, high-speed chop slamming, and continuous engine vibration without weld fatigue. Every unit comes fully encapsulated in a high-build TarGard epoxy coating to form an impenetrable barrier against standing bilge moisture and destructive saltwater pitting. Built to match the exact factory footprint, bulkheads, and deadrise pitch of the 2003 Donzi 35ZF, each tank is outfitted with welded mounting tabs, high-flow fill necks, integrated vent lines, brass fuel pickup elbows, grounding terminals, and pre-installed electronic senders—delivering a 100% direct drop-in replacement with zero structural modifications needed.

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.
