Fuel Sending Unit And Gauge Kit 125mm - 240-33 Ohm Marine Fuel Sender For Boats, Cars & Trucks

Alright, if you're dealing with unreliable fuel gauges or building a custom fuel system, this 125mm fuel sending unit is exactly what you need to get accurate fuel level readings.

The 240-33 ohm output is the standard for most fuel gauges, so compatibility is excellent with common dashboard gauges.

The 125mm length (about 4.92 inches) works well for many tanks, but here's the cool part - you can actually adjust it by loosening the center screw and rotating the components, or even cut it down if your tank is shallower.

Installation is pretty straightforward: mount the unit in your tank, connect the blue wire to ground, and the red signal wire to your gauge.

The metal construction is durable and corrosion-resistant, which is crucial for marine environments or any application where moisture might be present.

The operating principle uses magnetic fields to control reed switches, making it reliable, vibration-resistant, and safe for fuel applications.

What's really important is the installation tip: make sure you maintain at least one inch (25mm) of space between the float retaining collar and the bottom of your tank to ensure accurate readings across the full range.

This sender works with various fuels - gasoline, diesel, kerosene - and is perfect for boats, RVs, trucks, generators, or any custom fuel tank setup.

The quality feels substantial, and the design allows for flexible installation even in tight spaces where access might be limited.

Having an accurate fuel sender means no more guessing how much fuel you have left or worrying about running out unexpectedly.

The reliability of the magnetic reed switch design means consistent performance over time, unlike some mechanical senders that can wear out or become inaccurate.

Whether you're replacing a failed unit in an existing system or adding gauges to a project vehicle, this sender delivers the accurate, reliable fuel level information you need.

The value is excellent compared to OEM replacements, and the adjustability means you can make it work perfectly for your specific tank depth.

Seriously, if you're tired of unreliable fuel readings or building a custom fuel system, this sending unit provides professional-grade performance at a very reasonable price, giving you peace of mind about your fuel levels in any application.
