After installation and all . Readings were wrong . When it supposed to say full tank said empty and at empty tank shows full that’s trouble shooting it with a digital meter as well . Not recommended. They should just replaced it for another instead waste your time to shipped back

I wanted to retrofit a 6-gallon portable tank with a fuel level sender for my boat. I had found an article on hackaday where someone had done just that, so I knew it could be done. I had to measure the depth of my tank, allow about 1/2" of space below the sender, and then round down to the nearest inch. You have to play some games to get the bolts in from below, but it's all manageable.I had read that a lot of these sending units essentially just have a stack of reed (magnetic) switches connected to a series of resistors, so I was expecting these results at least. In the case of my 8" RUPSE Fuel Sender, there are apparently only 7 (actually maybe just 6) switches inside, so there are only 7 levels - or ranges - that it can sense. I've included photos of the high and low marks for each level range, along with the measured resistance. I don't yet have my fuel gauge, but any gauge compatible with 240-33 ohms should work just fine.There is some hysteresis when moving the float up and down. In other words, there's not a fine line where you're either in one range or the next. Once the float trips the next switch going one direction, you have to move a bit back in the other direction before the switch trips back. (This is much like your home thermostat - it typically has to be 1 degree above the set point to turn the A/C on, and 1 degree below the set point to turn the A/C off. This prevents a system from fluttering between two states too quickly.)I was surprised, however, that the lowest levels have the largest changes in resistance. I haven't measured the heights and plotted them vs. resistance; maybe it's on a logarithmic scale??? Anyway, I certainly hope that the gauge responds accordingly. Otherwise, if it's a linear scale, then it's going to look like you're consuming very little fuel for the first half of the tank, and then it's going to drop fast on the gauge for the last 3 levels.At any rate, all that is stuff I can get used to after some time on the water. In the end, ANY ability to see an indication of my remaining fuel while sitting at the helm will be a huge improvement over guessing -- especially when I'm on my last tank.I think I'll be happy with this sender and would likely buy another like it. As long as you know what to expect and you don't require a continuously varying resistance throughout the entire level range, you'd be happy with it, too.

I ordered the sending unit to replace one in my boat. Everything looked great and the fit and finish was fine but when the sending unit was wired to the fuel gauge we realized that the polarity was reversed. When the tank is full it reads empty and when the tank is empty is reads full. This could not be fixed by switching the wires leading to the gauge, it was a wiring problem with the sending unit.
