Boat and RV owners, this Wonfly fuel sender unit is a solid replacement when your old one gives out. Made from heavy-duty 316 stainless steel that can handle marine environments without corroding. It uses a reliable OKI reed switch technology rather than the problematic thick-film swim arm type, so no moving parts to break or adjustments needed for different tanks. The SAE 5-hole mounting pattern with NBR gasket creates a tight seal that won't leak, and the M5 screws and quick wiring terminals make installation super easy - about 15 minutes total if you're somewhat handy. The 6-inch length (15cm) works for many standard tanks, but measure your tank depth first - you want the sender to be about 1 inch shorter than plastic tanks or 0.5 inches shorter than metal tanks to avoid hitting the bottom. The 240-33 ohm signal output works with most standard fuel and water level gauges in boats, cars, trucks, and RVs. The construction feels quality and should last much longer than cheap replacements. If you need a different size, they offer other options too. Definitely a reliable solution for getting your fuel gauge working accurately again without breaking the bank.
