My 2000 scudo 1.9el a couple months back use to go all the way until fuel light come on. Now it runs out when the fuel indicator has a quarter of a tank left.... Does anyone know why??

sounds like fuel sender in tank not working correctly might be sticking

I have the same problem 1/4 of a tank then 1 day it moved to 3/4 now it don't move at all. first thought was the sender. you need to remove the tank to get to it. other way is cut a hole in the floor above the sender to get access. But then i was told you can have a fault on the clocks and fuel gauge. i just use the mileage trip 35 miles to a gal. good luck
