KUS USA SSS Fuel & Water Level Sensor

This was a OEM replacement on my boat fuel tank. It works perfectly.

As described

Replaced the original fuel level sending unit in a vintage 1990 Correct Craft Ski Nautique. It had two wires (a black and a pink wire) from the fuel gauge to the unit and one (green) grounding wire from the fuel fill inlet. I connected the pink wires to each other and the green and black wires to the black wire on the sending unit.Works perfectly so far. We will see how long it lasts...

Our boat came with a WEMA brand of fuel sending unit which delivered more than 20 seasons of reliable service. We wanted to replace it with the same brand and quality, but had a hard time determining whether "KUS" somehow became a descendant. From a website "We are pleased to announce the integration of Wema USA Incorporated into KUS Auto Group. KUS Auto has been a long time partner and supplier of products and components to Wema USA, Incorporated."Happy to report that the item I ordered from Amazon is of the same high quality as our original, including the gasketed hold-down screws, the main gasket, and a stainless steel housing with a quality slide float. Installed flawlessly, and quite pleased. RECOMMENDED

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.

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.

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.

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.
