Moeller Gauges & Sending Units

Moeller Gauges & Sending Units: Precision Fuel Monitoring for Every Vessel

When it comes to knowing exactly how much fuel is left in your tank, accuracy and reliability aren't optional — they're essential on the water. Moeller Marine has spent more than 25 years earning its reputation as the industry standard in marine fuel system design, and nowhere is that expertise more evident than in their line of Gauges & Sending Units. Whether you're running a bass boat, a center console, or an offshore fishing vessel, Moeller's fuel-monitoring components are engineered to give you dependable readings every time you check the dash.

A Complete Line Built Around OEM Compatibility

Moeller offers the marine industry's most comprehensive line of OEM-compatible fuel senders and remote gauges. That means whether you're replacing a worn-out factory sender or upgrading an older analog gauge, there's a Moeller solution designed to integrate seamlessly with your existing hardware. Moeller offers a complete line of fuel level sending units designed for top mounting in aluminum, plastic, or stainless steel fuel tanks on all types of marine vessels.

Mechanical, Electric, and Reed Array — Three Technologies, One Brand

Moeller's senders range from mechanical and electrical designs to reed array and reed switch operation. This breadth of technology means you can find the right sender for your specific tank and gauge configuration rather than settling for a “close enough” fit.

• Swingarm Electric Sending Units: A complete line of universal swing-arm fuel senders spans 4-inch to 28-inch tank depths, making them a true DIY product — the consumer measures their tank depth and sets the swingarm float to the exact length needed for accurate fuel level readings.
• Reed Array Sending Units: Moeller's reed array senders provide highly repeatable level readings with no moving contact points that can wear over time, making them an excellent choice for boaters who demand long-term consistency.
• Dash-Mounted Electric Fuel Gauges: Moeller's swingarm electric sending unit kits include a dash-mounted gauge for 4" to 28" tank depths, corrosion-resistant components, and a float that rotates in 90-degree increments.

Built to Marine Standards — Not Just Close to Them

One of the most important differentiators in Moeller's gauges and sending units category is their commitment to meeting the toughest marine regulations. All Moeller fuel senders and gauges are ethanol-compliant and exceed current NMMA and ABYC specifications. In an era when ethanol-blended fuels have become the norm at the pump, this compliance matters for long-term component integrity.

Regardless of the configuration, all Moeller sending units feature calibration of 33–240 ohms, a 5-hole gasket and screws, and compatibility with a dash-mounted gauge. This universal calibration standard ensures that Moeller senders pair correctly with virtually any aftermarket or OEM dash gauge calibrated to the industry norm. Internal components will not rust or corrode, a critical design feature for saltwater and high-humidity marine environments.

Why Moeller Stands Out in This Category

Moeller Marine has furnished fuel systems or components to nearly every boat builder, from bass and ski boats to offshore saltwater fishing vessels. That OEM-level trust translates directly into their aftermarket sending units and gauges. Moeller's reputation is built on innovative engineering, quality construction, and award-winning service. With 20 products available across the Gauges & Sending Units category, boaters and mechanics will find both direct-replacement senders and complete gauge-and-sender kits suited to a wide variety of boats and tank configurations.

Whether you need a standalone sender for a known-depth tank or a complete universal kit that you can size yourself dockside, Moeller's gauges and sending units deliver the peace of mind that comes from knowing your fuel level readout is accurate, durable, and built to the standards the marine industry trusts most.
