Replacement Direct Sight Gauge for Mechanical Fuel Senders
A direct-reading replacement sight gauge designed for use with mechanical float-style fuel senders. Works as a standalone direct sight gauge or with a conversion capsule to gather fuel level data from the float arm. Provides a clear, real-time visual of fuel level directly at the tank — no electrical connection required for basic sight gauge operation.
Note: Because this gauge uses a float mechanism, the reading will fluctuate slightly as fuel moves around the tank while underway. This is normal behavior for float-based systems.
Features
- Compatible with mechanical float-style fuel senders
- Can be used as a direct sight gauge or with a conversion capsule
- Reads fuel level via float arm movement
- No electrical connection required for direct sight gauge operation
- Replacement part — fits existing mechanical sender installations
Common Applications
- Replacing a worn or damaged sight gauge on an existing mechanical sender setup
- Adding a direct visual fuel level indicator at the tank
- Upgrading older mechanical sender systems without rewiring
Parts Desk Insights
Best Use Case: This gauge is the right call when a customer has an existing mechanical float sender already installed and just needs to replace the sight gauge component — avoiding a full sender replacement. It's also a good fit for boats where a simple, no-wiring visual fuel level check at the tank is preferred over a dash-mounted gauge. Pair it with the Moeller Swingarm Mechanical Sending Unit for a complete mechanical sender and gauge solution. For customers who prefer an electrical dash gauge setup, point them toward the Marine Fuel Gauge Kit with In-Tank Sender or one of the Fuel Tank Senders in our catalog.
