Review: 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 desertcart. 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
Review: Get this one - Works great, perfect fit. We'll constructed.

If You Have to Drill the hole, Diameter 1-1/2"(38mm) Hole Would be Perfect.③AODITECK Sender is with Non-Linear Output, It can only match with standard gauge with Non-Linear signal
