Review on ⛽ 100TECH Fuel Sending Unit: Marine Boat Vehicle Truck RV - 240-33 ohms, 15" (380mm) - Fuel Water Level Sensor & Gauge Sender by James Ortega

I pumped out ethanol that the previous owner put a hose through the transmitter opening. I replaced it with this one as I didn't have a floor or seats. The old one still worked but might as well since I was so deep! I measured from the top of the tank to the bottom, it's 7 inches. I ordered a 6" and it won't bottom. I put 5 gallons of clean gas in it and it didn't fix it. It registered in the low zone at 10 gallons so I'm pretty sure it didn't is near the bottom of the tank, and it will appear like I have less gas than I actually have! (I think it's good!)
