Buy this fuel sender unit. You will not be disappointed !
I like that it worked. Best part is that the shaft is made of stainless steel. My old fuel tank sender unit was plastic and junk. As you can see from the pic, the plastic one bent and failed. I had no functioning gas gauge. This new one was so easy to install. No issues with lining up the gasket and holes. Only complaint I had was that the screws supplied were fine thread. And the tank accepted standard size threaded screws. I was able to use the old ones. I tested it out and the gauge works. Seems very accurate as well. Great float system. Much better than those bobber type fuel sensors. I would def recommend getting this. I bought the 8” one because my tank is 10” deep. I prefer to know that I have enough fuel in reserve. I would def buy this again. High quality. Price was great and it arrived at my door in less than 24 hrs. Delivered by Amazon. USPS would have taken almost 5 days to deliver. Satisfied customer here. And I never leave reviews. That’s how much I like this product

Great replacement fuel gauge!
This gauge was easy to set up and easy to configure for whatever fuel level sensor you have. Even if you don't know the Ohm range of your sensor, you can hook up this gauge and try the different settings until you find the proper one. I highly recommend hooking up the new gauge and sensor on the bench first! That allows you to easily test both gauge and sensor and configure it prior to reinstalling. I love the expanded gauge markings on the face making it easier to get a more accurate idea of fuel level. My one and only complaint is the connector on the back is not sealed and would definitely allow moisture to collect inside. I ended up slathering on sealant to make it more moisture resistant after plugging in the connector. Now my only remaining task is to decide what color to set the backlight!

Perfect!
I have a 1989 Baja Islander 190 with a 4.3 Mercury V6 Alpha One. This works well with the OEM tank and gauge. The wire is long and sensor is accurate. The screws are strong and don’t strip. They are Phillips head which is nice. The holes only align one way so make sure to keep rotating until you get it perfect. It also shipped fast and arrived faster than expected.

La jauge installer par le haut du réservoir fonctionne à l'inverse. Pourquoi ne pas donner une description identique au photo ou vidéo qui y correspond. Solution plus de détail pour sur le produit serait mieux.
