The fuel gauge on my 94 Limited hasn't worked (properly*) for probably 7 or 8 years. Every time I get to 300 miles on a tank I'd refill. Well I finally got around to the task of cutting a hole in the floor, pulling out the old sending unit, removing the original pump and placing it on a new sending unit with a new strainer, and placing that back in the tank. And replaced the fuel filter. Turn it on and still no reading at the gauge... fffffuuuuuuuuuuuu-!!! What do I check next? *I mentioned it hasn't worked properly for 7 or 8 years. What I mean by that is the gauge would often show an initial full reading when I turned the Explorer on. But over the course of a couple miles the gauge would slowly but surely drop to empty and remain there for the duration. This morning when I turned it on after replacing the sending unit it just stayed dead on the empty side. I threw my hands in the air and came in to take a multi-hour/beer long break. Please advise and thanks in advance!
