Sunshine Marine Tanks has been building our reputation one tank at a time


Benny Diaz

40 years ago Benny Diaz founded Sunshine Marine Tanks and established his business to service the marine industry in South Florida. Since then, Sunshine Marine Tanks has been building its reputation one tank at a time.


Sunshine Marine Tanks has become synonymous with integrity, quality, and consistency.

The superior workmanship of our marine tanks is what inspires the confidence of new customers and the loyalty of established business relationships.

Today, Sunshine Marine Tanks is still a family owned and operated business that continues to build on Benny’s vision: to deliver the highest quality custom marine tanks, utilizing only prime grade aluminum alloy, at a reasonable cost.


The pride we have in our aluminum tanks is recognizable in the craftsmanship of every fuel, water, oil, and holding tank that we produce. Each tank meets or exceeds every standard set forth by the marine industry and the US Coast Guard.

Every tank exceeds industry and US Coast Guard, ABYC, and NMMA standards

Every tank is competitively priced

Every tank is delivered on time and within budget

Every tank has the indelible Sunshine mark of excellence
