The Fuel Sending Unit and Gauge Kit uses a reed switch design in a heavy duty 316 stainless steel housing and delivers a 240-33 ohm signal, which makes it a straightforward swap for many mechanical lever senders. It is best for boat and vehicle owners who want a more stable reading in rough conditions and prefer a compact unit with an SAE 5 hole mounting pattern and no tank-specific adjustment required.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy duty stainless steel:\u003c\/strong\u003e The 316 stainless steel construction provides corrosion resistance and long term durability in marine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed switch output:\u003c\/strong\u003e A reed switch sensor gives a steady, reliable 240-33 ohm signal that resists erratic readings from movement or vibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo tank adjustment needed:\u003c\/strong\u003e Designed to work without additional calibration for most tank setups, simplifying installation and replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAE 5 hole mounting:\u003c\/strong\u003e Common mounting pattern makes it compatible with many existing tanks and reduces the need for custom adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide application:\u003c\/strong\u003e Works as a fuel level or water level sender for boats, cars, trucks and other vehicles, making it versatile for fleet or multi-vehicle use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength guidance:\u003c\/strong\u003e Built-in design requires the sender length to be about 1' less than plastic tank depth or 0.5' less for metal tanks to avoid bottom impact.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe unit suits boat owners and drivers of cars or trucks who need a rugged replacement sender that maintains stable readings when the vehicle experiences constant motion or vibration.
