Send us your engine room dimensions, fitting locations, and whether it's diesel or gas. We'll design and quote the full tank — including pressure test certification.
DolFab holds Lloyds, ABS & USCG certification for structural welding, plus a hot-work permit specifically for fuel tank fabrication and repair. Every tank meets ABYC H-24 (gasoline) or ABYC H-33 (diesel) standards.
