One problem related to fuel pump has been reported for the 1998 Kia Motor Sportage. The most recently reported issues are listed below.
Fuel tank is leaking, widespread problem, kia will only replace tank if the leak is on the very bottom of tank. They are saying mine is leaking at the seam. I very dangerous problem no matter where the tank is leaking. I only hope noone has a fire because of it. I have to pay the extremely expensive bill. I was told not only do I need the tank I will need the fuel pump assembly also and possibly more parts. The total approximately $1000. 00 to have installed. This is bs an outrage. Had I known the problem with the kia's I would never have purchased it.
