The Seachoice 50-15571 is an 18-inch (450mm) reed switch fuel sender built for marine fuel tanks, compatible with the standard 33 ohm (full) \/ 240 ohm (empty) gauge resistance range used across most marine fuel gauge systems.\u003c\/p\u003e\u003cp\u003eThe reed switch design has no moving mechanical parts — eliminating the most common failure point in traditional float-arm senders and delivering consistent, accurate readings over the long term. Stainless steel immersion tubes resist corrosion in fuel environments, and the included SAE 5-hole gasket ensures a clean, leak-free fit on standard tank openings.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e18 in.

If your fuel gauge is reading erratically and the gauge itself tests correctly, the sender is the most likely cause. Always measure your tank depth before ordering to confirm the correct sender length.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThis sender works with any standard 33\/240 ohm marine fuel gauge.
