One problem related to auxillary tank has been reported for the 1998 Jeep Cherokee. The most recently reported issues are listed below.
I just found out I have a cracked manifold, my driver side door has broken put a new part in it and now that is broken,I have also had to put a new transmission in it with only 148,000. 00 miles. In 2006 I had to fix the gas tank because it was broken too. Is this not a recall problem????? any of these, I have had the Jeep since 2000 and I bought it when it had 20,000 miles on it. Please help because this is 2012 and I only have 156,000 miles on it now. Thank you.
