114250-55122 Premium Diesel Fuel Filter
High-Performance Filtration for Yanmar YDG & SDMO Generators | Replaces Fleetguard FF42103, Baldwin PF7826 & HiFi SN 21593
Engineered for Fuel Purity and Power Stability
The AYREST 114250-55122 Fuel Filter is a high-precision filtration element specifically engineered to safeguard the delicate fuel injection systems of Yanmar YDG series generators and compact marine power units. Utilizing state-of-the-art oil-resistant composite paper, this filter provides a filtration precision equivalent to OEM standards, effectively capturing paraffin, water droplets, and micro-contaminants that can cause catastrophic injector wear.
The structural advantage of the 114250-55122 lies in its compact straight-through design. This architectural choice maximizes fuel permeability while maintaining an exceptionally low pressure loss across the filter media. By ensuring a steady and clean fuel flow, the filter prevents engine "surging" and maintains stable RPM under varying load conditions.
Our pressure-resistant housing combined with precision-automated pleating ensures that the filter media remains structurally sound even under high-temperature industrial environments. Whether integrated into an SDMO standby generator or a Mase marine power system, the 114250-55122 serves as a reliable core component for maximizing equipment uptime and extending fuel system service intervals.

Expert Technical FAQ
Q1: Why is the straight-through design critical for Yanmar YDG generators?
A: Compact generators often rely on gravity or low-pressure pumps for fuel delivery. The 114250-55122 straight-through architecture minimizes resistance, ensuring that fuel reaches the injector pump consistently even in high-ambient-temperature environments where vapor lock might occur.
Q2: Is the "Premium Cured Composite Paper" better than standard cellulose?
A: Yes. Cured composite paper is resin-impregnated, which prevents the fibers from swelling or breaking down when exposed to diesel fuel or biofuels over long service periods. This maintains absolute filtration efficiency until the next scheduled maintenance.
Q3: Can this filter handle biofuels (B20/B100)?
A: The 114250-55122 utilizes an oil-resistant composite media specifically tested for compatibility with standard diesel and biodiesel blends, resisting the chemical degradation often associated with biofuels.
Q4: How does the 114250-55122 prevent engine surging?
A: Surging is often caused by intermittent fuel flow or air bubbles. Our precision automated pleating provides uniform fuel passage, maintaining stable pressure and eliminating the "pulsing" effect caused by unevenly blocked filter elements.
Q5: What is the recommended service interval?
A: While equipment manufacturers typically recommend replacement every 200-500 hours, we suggest inspection every 100 hours if operating in dusty construction or agricultural environments to ensure peak power unit stability.
