Fuel Level Probe 4in- 12in 240-33 Ohm

The Fuel Level Probe 4in–12in 240-33 Ohm by ATL Fuel Cells is a precision sender unit designed for high-performance fuel system installations and aftermarket tank applications. Whether you're building a race car, restoring a classic, or upgrading to a quality fuel cell system, this probe provides accurate real-time fuel level readings to your vehicle's gauge cluster. ATL Fuel Cells manufactures OEM-grade components trusted by motorsports professionals, and this sender meets the demanding accuracy requirements of serious automotive builds where fuel management directly impacts performance and reliability.

This fuel level probe operates on a 240-33 ohm resistance range, a standard specification that ensures compatible integration with most aftermarket gauges and fuel management systems. The probe's adjustable length accommodates tanks with internal depths between 4 inches and 12 inches, giving builders flexibility across multiple platform conversions and custom fabrications. The design utilizes a float-arm mechanism that moves smoothly across the full resistance sweep, eliminating dead zones and providing linear fuel level indication critical for tuning fuel injection systems or monitoring consumption during extended driving sessions. At just 0.5 pounds, the probe adds minimal weight while the compact dimensions (4.2 x 3.05 x 13.2 inches) allow for tight installation spaces common in modified engine bays.

This probe is ideal for owners retrofitting fuel cells into street rods, drag cars, or rally builds, as well as mechanics upgrading fuel system accuracy on fuel-injected conversions. The 240-33 ohm range ensures compatibility with both vintage mechanical gauges and modern electronic fuel level monitoring systems when paired with appropriate gauge senders. Installation requires basic electrical connections and proper calibration to your specific tank geometry; consult your fuel management system documentation or gauge manufacturer specifications to confirm ohm range compatibility before purchase. This component is essential for any serious modification where precise fuel level data supports both performance tuning and operational safety.
