Fuel pump Question

[Twisted4x4]

a guy at work has a 98 explorer sport with a 4.0 he says the fuel pump is bad and asked if i could fix it for him. he called the parts stores and they told him $100 for fuel pump. are the fuel pump/sending units all one piece on these or are they two seperate parts like in the older rangers? i changed out a fuel pump in my 89 ranger and the pump itself was only around $40 while the sending unit was over $100. any help is appreciated

being its a 98 id say all one unit most cars were switched over to the big plastic pos by this time
