The combination of a 10mm resolution reed switch sender and a smooth-sweeping stepper motor gauge makes the system particularly valuable for shorter tanks and marine environments. Installation is straightforward and the stainless steel construction promises longer life in saltwater use.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh resolution sender:\u003c\/strong\u003e The 10mm resolution provides much finer, continuous fuel-level readings than coarser 21mm senders, which helps in short tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-linear signal matching:\u003c\/strong\u003e The sender outputs 240-33 ohms (240 ohms empty, 33 ohms full) to match standard non-linear gauges and avoid calibration issues.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e316 stainless steel construction:\u003c\/strong\u003e The sender body, rod, gasket and mounting screws use SUS316 for improved corrosion resistance and longer service life in marine settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed switch magnetic design:\u003c\/strong\u003e No swing arm float means fewer moving parts, reduced slosh error and smoother readings in rough water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooth sweeping gauge:\u003c\/strong\u003e The gauge uses stepper motor technology, an 8-color selectable backlight and a curved lens to improve night readability and visual contrast.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete kit and hardware:\u003c\/strong\u003e SAE 5-hole mount, NBR gasket, SUS316 screws and quick wiring terminals are included for a one-stop install.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is aimed at boat owners and operators who need reliable, accurate fuel-level information, especially in shorter tanks where finer resolution really matters.
