Since 1946, Port of Egypt Marine has been a fixture on Long Island’s North Fork, serving generations of boaters drawn to the region’s protected waters and prime coastal access. Today the marina features 132 single-loaded slips, a fuel dock, a dockside restaurant, pool and cabanas, a service department with certified Yamaha technicians, and a robust boat sales operation. The marina offers easy access to Greenport, Shelter Island, the Hamptons, Montauk, Connecticut, Newport, and Block Island. Its naturally protected basin makes the marina a trusted stop for both seasonal slip holders and transient boaters.
Operating a marina of this scale brings real pressure, especially during peak season. Boating traffic surges from early spring through late fall, with long holiday weekends and early-morning fishing runs putting constant demand on the fuel dock.
“When you run out of fuel, you’re not just out of product; you’re disappointing customers,” says Yvonne Lieblein, who took over management alongside her cousin in 2019. “And you can’t measure the ripple effect of that disappointment.”
Fuel reliability, pricing visibility, and consistency aren’t nice-to-haves at Port of Egypt Marine, they’re essential.
A Smarter Way to Manage Fuel

Before partnering with Sprague, fuel management was one of the marina’s biggest stress points. Monitoring tank levels was manual. Deliveries were inconsistent. Running out of fuel, especially during holiday weekends, was a recurring problem.
“It was literally a nightmare,” Lieblein recalls. “We even have a sign that says, ‘sorry out of fuel’ in the back that, I try not to ever look at, but I keep it there because it just makes me happy that we never have to use it.”
As part of a broader fuel dock overhaul, including new double-wall tanks and modern dispensers, Port of Egypt Marina made the decision to switch to ValvTect® Marine Fuel and partner with Sprague. From the very first call, the difference was evident.
“The communication from day one was outstanding,” says Lieblein. “Sprague was responsive, professional, and very clear about how everything worked. The process to become a ValvTect provider was incredibly smooth.”

Port of Egypt also took advantage of digital tank monitoring, which allows deliveries to be proactive rather than reactive. Because pricing updates are communicated daily, the marina can adjust dock prices confidently and transparently. Invoicing and reporting are also timely and reliable.
Most importantly, the fuel itself became a draw.
“Our customers seek out ValvTect,” Lieblein explains. “They’ve learned what makes it different, and many come here specifically for it.”
Port of Egypt also tapped Sprague’s expertise to help ensure dockhands understood ValvTect‘s benefits and could confidently explain them to both experienced boaters and newcomers alike. Rebate programs and signage further reinforced the value at the dock.
Reliable Fuel, Fewer Interruptions, and a Better Experience for Everyone

Today, fuel is no longer a daily concern at Port of Egypt Marina and that peace of mind is transformative.
“To know it’s being monitored, that deliveries are handled properly, and that we’re always informed, you really can’t put a price on that,” Lieblein says.
With Sprague managing fuel reliability behind the scenes, the marina’s team can focus on what matters most: customer experience. Dock attendants aren’t stuck fielding complaints or apologizing for outages. Management isn’t chasing deliveries or reconciling delayed invoices. Boaters arrive confident they’ll get premium fuel, even during the busiest weekends of the season.
That confidence extends to customers as well.
“ValvTect gives people peace of mind,” Lieblein notes. “They may not talk about it every time, but it helps them relax and enjoy their boat more. They know they’re taking care of their engines, and that matters.”
Four years into the partnership, Sprague remains a steady, trusted presence, that is accessible when needed, and unobtrusive when everything is running smoothly.
