Recently bought my son an 04 XLT with 3.0. When I bought it the seller told me the sending unit was bad and noted the gauge would go from full to about 3/4 tank at the lowest. Been using the odometer to keep track of when to re-fuel. Today the gauge dropped all the way to E and now the low fuel idiot light is on. This is my first ranger so I don't know anything about the fuel pumps. If I am reading right the fuel sending unit and fuel pump are two separate parts. I am curious if these fuel pumps are prone to go bad, thinking if I am going to drop the tank or pull the bed would you guys replace the fuel pump while I am there, or are they reliable enough it likely won't be an issue? The truck has 115K miles on it. Also for those of you who have done this, is it preferred to drop the tank or move the bed?
