KUS USA SSS Fuel & Water Level Sensor

Simple, reliable, easy installation. Comes with gasket and new screws, but you might have to re-use your original screws depending on the thread pitch of your tank's holes. No big deal. These a far more reliable and accurate than the old float on a swing arm style senders. Just remove your old sender and tape measure the depth of your tank and subtract one inch for sender tube length, and order the correct length here on Amazon. You allow one inch clearance for tank expansion or change in shape between full and empty, and you'll have a little reserve fuel even when the gauge reads empty.

Used this to replace the sending unit on my G3 Golden Eagle. It was a perfect replacement for the old one and worked as expected. Quality and Craftsmanship are excellent as well. Very pleased.

tried lots of other methods of measuring water usage - flow meter etc, but this physical measurement is the way to go!

Very well made, has stainless steel stem and flange. Came with five #10-24 flanged stn. stl. machine screws (combined hex and Philips drive) with a full gasket and with five gasketed washers. I purchased the 5.5" stem length. Using an ohm meter I measured 9 changes/steps in the output as I slid the float down the stem top to bottom. My dash gauge now reads in about 1/8" increments/steps from full to empty. I replaced my one year old swing arm fuel sending unit with this unit. I could not depend on the reading of the swing arm sending unit in my boat's 6" deep welded aluminum fuel tank. I am very satisfied with this new sending unit.

I replaced the OEM's arm-type fuel sender in my Hydra-sports "Vector", due to its intermittent failure. I thought that utilizing the "reed switch" type would be a better component, so I went with this model - after measuring the tank depth.I found its color code to be "reversed" compared to my existing harness, but that was easily determined/corrected by using an Ohms meter to confirm which wire went to the battery ground. I then connected the unit to the harness before installing it into the tank, to verify its operation. Sliding the ring up and down the tube showed the expected response on my fuel gauge. (Just don't forget you need the battery and ignition switches "on" for the test).With all power "off" for safety, I then installed the sender per instructions. It is a complete kit, containing the gasket and the special screws for installation. The only PITA is getting that 5-point "star" screw hole pattern correct. It only aligns correctly one way and it's just difficult to see the difference without "some" trial and error, (especially if you coated the gasket with silicone). However, I eventually managed to get it right and cross-tightened the fasteners to facilitate completion.I knew the former sender's reading on the tank's contents, so with the new sender installed, it was good to see that it agreed with the former reading. This tank depth measured 17.5" from its bottom, to the top, (inside) - so I had to select this unit as the closest match, (the "guide" says to buy 1" shorter than actual internal tank space). But I decided that if this one read nearing empty "sooner", (due to that extra half inch of the fuel level) it would be better than being in error in the other direction, (showing fuel when there is none!).I recommend this unit, as it appears to be nice quality and includes everything you need in the package to make the replacement with ease. I would recommend adding silicone or your favorite sealant to the gasket, but if surfaces are clean and true, it may not be necessary.

Replaced a non-functioning unit with this one and it works great. Very accurate and easy to install. Used existing wiring with no issue

After the Capacitance senders in both diesel tanks malfunctioned this was recommended by mechanic and the only 21 in. one with high Amazon ratings Works great in fwd tank but unfortunately the float diameter to large for the aft tanks small diameter sender tube or I would order a 2nd one.

Great product just would not work with my gauge

Seems to be well made. Functuon tested with guage prior to install and had perfect range of travel. Seems to go up in about 9 or 10 separate steps, as to be expexted with a reed switch type transmitter. Much more reliable than the old style swing arm type.

Measure tank depth to ensure it will fit, give enough head room to allow the sending unit to not hit the bottom of the tank, Used on a 96 Four Winns Horizion 17.5' boat with inboard 80L fuel tank. Sending unit worked well and accurate (for a boat) better than the OEM arm+float style that this replaced. Modified existing 2 wire harness to connect to the wiring pigtail provided on the new sender without issue.

all good works fine

Worked very well and helped correct the issue I had with my new gauges not being the correct resistance reading for my old sensor.

I ordered the 11 1/2” (to fit my 98’ Mastercraft Sportstar 19) just two days ago and got it time for my summer vacation, thanks Amazon! . Please note, I had to use different screws (than the ones that came with the sending unit) to match the old screw pattern, other than that this kit is an awesome retro fit. Will monitor and report back when we return from holidays!
