100TECH Marine Fuel Sending Unit Float Replacement 19"(480mm) for Boat Vehicle RV Fuel Sender Gas Tank Sending Unit Diesel Level Sending Unit Water Level Sensor Fuel Gauge Sending Unit 240-33 ohms

I used it on my boat to replace the water level rod. I ordered the same size, works great with existing meter.

Very easy to follow instruction and easy install. Comes with screws but they were a different thread so I just used the old ones.

Very fast shipping and good quality. But the bold holes are NOT standard specs.. after getting the sending unit. I wired it up heat shrink everything and installed the gasket and sending unit right. No matter how I rotated the bolt holes. They would not line up evenly. So after 30 mins of wiring and trying to get it lined up. I had to go to west marine and go back to the stick style sending unit and that bolted right up in matter of seconds,I highly do not recommend this unit,..Over all the quality is great but the SPECS are way off for a standard 5 bolt hole pattern.Send it back we will see if they refund my money,,,

my application in a camper needed a lot of creativity to install. Water tank was too shallow for gauge so had to build a pvc collar. Tank gage reads 7/8 when filled. Additionally i put in a 2nd gage outside where the fill port is, with both connected they read just less than 1/2 when completely full. I'm actually happy to have both gages so it's a win for me.

Ohmed out as stated, 32.6 *full and 421.8 *empty*Gasket and flange lined up correctlyI couldn’t use the provided screws, they weren’t the same threads as my tank so I Just used the pre existing ones. Not a big deal I understand this works for a wide range of tanks and new installs.They also have a video with the wires labeled.My gauge is now reading correctly and I am pleased with the productIf any issues occur I’ll update review
