Review on Fuel Level Sensor Gauge For Boat Car Truck RV - 6.8" (175Mm) Stainless Steel RUPSE Fuel Sender Unit by Bruce Willam

The system is ok for the money, no moving float arm to break, probably last longer in my boat but.It changes level in about 16 steps, not analog.This unit works off of what i assume are reed switches. The magnet float slides up and down the rod and switches resistance along the way in steps. So when you get to almost empty it goes from 8% to zero. Or 100%-92% 86% 78% ect in steps. Still i would buy again for inexpensive gauge.
