Rupse Fuel Sender Unit Boat Fuel Tank Sending Unit Fuel Water Level Sensor Stainless Steel Fuel Sender and Fuel Gauge for Boat Car Truck RV 6" (175mm)

I installed the transducer/sending unit on my boat gas tank, which was made in 1972 and the five bolt pattern does match up! Took a bit of rotating as the bolt pattern is not symmetric. I bought the 6.8” transducer as my tank is 7.5” tall. The wiring instructions/schematic was detailed enough to easily wire the unit. I’ve got a newer motor and ignition set up so I was able to wire directly to the ignition stud of the newer tachometer. The included gas gauge fit perfect in my old gas gauge cut out. I turned on the ignition and the gauge booted up with a needle sweep and then slowly climbed up to the actual fuel depth in my tank, which I feel is accurate. The back light is nice and bright and the variety of backlighting colors is more of a novelty and I think my kids will get a kick out of it! Happy so far with the set up, but we’ll see how solid this set up is when I get it out on the big water of Lake Michigan. Will update this review if necessary. Very good product so far at that price point.

Works fantastic. I use it on a 73 vw beatle. So far seems to be working well. Only thing i would like is that the guage would be pre set for the fuel float instead of trying to figure out how to set it. Also that the wires would have female connectors instead of having to extend the wire by crimps. Other than that, easy install

I purchased this fuel gauge for my VW rail buggy. I had tried several different brands and types of gauges, but none of them worked as they should have. This gauge is by far the best one I have used. The gauge is nice, and heavy duty. It goes through a start-up check to make sure it is reading correctly. If I were to have any complaints, it would only be how the gauge readings change so quickly with the movement of the fuel in the tank. If you want to get a proper reading, it is best to be sitting flat and not moving. Otherwise, this is a great deal!!

works, although the instructions are in poorly translated english. also, it bugs me that the pins are not numbered in any sort of order, and the pin numbering in the instruction sheet does not match the diagrams online, so pay close attention to the diagrams in the instruction sheet. it's the same physical layout as online, but everything is numbered and drawn differently. just plain sloppy documentation. also, a "long press" on the button cycles it through modes designed to accommodate different sensors. so if it is reading wrong or backwards, look at the chart in the instruction sheet. this is also poorly explained. also, it does not seem to be analog. the reading isn't continuous analog, it moves along in discrete steps. it's "full" for a while, then it suddenly jumps to "3/4" and then stays there for a while, the jumps to "1/2" and so on.

worked well in my fuel tank
