The fuel level sending unit in my 2001 Chevrolet silverado is totally inaccurate. About a year after I purchased the truck in 2005 the fuel gauge became sporadic, randomly going to empty then back to full and every where in between. This would mostly happen when the truck was lower on fuel. As the next couple years pasted by it got worse and worse. Finally in 2009 I replaced the unit and fuel pump. The kit included and new connector for the wiring harness, so I was hopeful this would resolve the issue. Well after about a year or less I started having issues again. This time the fuel gauge does not randomly go all the way to empty or full randomly, but once it gets past 3/4 of a tank it cannot be trusted anymore. Especially once you get past the 1/4 of a tank it looses all accuracy. Allot of times it when I start the truck it will be at 1/8 of a tank but as I start driving it will go up to a 1/4 of a tank. Or visa versa. I live in a flat part of the country and this has nothing to do with hills. Last time I filled up it said I had a little less then a 1/8 of a tank (about 3 gallons, 26 gallon tank) and when I filled it up I put almost 26 gallons in. I would replace it, but I don't want the same thing to start happening again.
Erattic fuel gauge operation: fuel gauge reads empty at random times,amount of fuel in tank isn't a factor. Gauge drops quickly from 3/4 to low fuel warning (within a few miles).
Gas gauge registers empty every time gas tank is filled and thereafter until x amount is used and also at random times.
