I have a 92 MJ 4.0 all stockstock that has recently had the fuel pump and sending unit replaced. Before this occurred the original owner never noted the has mileage to a tank of gas. There are no apparent problems with the truck like MAP sensor, o2 sensor, vacuum leaks our anything as it all has been replaced and or fixed. Since having the new fuel pump and sending unit replaced, after a fill up the gas light is on and the tank its showing empty after 190 miles. So with all that said, how many miles should I expect to get out of tank of gas?
