Im having problems with my NEW Fuel Sending Unit. Help!
Sunday morning me and my brother put the truck on the car lift, drain 25 gal. of fuel, pull the fuel tank, replace the entire fuel tank sending unit. We then put everything back together, and put fuel back in the tank. The gauge was still on empty.... I said screw it, im tired of messing with it. By the time I got home, I had about 3/8 of a tank. I fill it up that evening, gauge reads Full. Excellent. NOT. After about 80 miles of driving, im already reading under the 3/4 of a tank mark. I know my truck doesn't get that bad of mileage. What gives? Is there a reset or something, or does the new unit have to "learn" what is full and what is empty. P.S. I have the 39 gallon tank.
Sorry for the long post.
