new[to me]x5

[Rondo]

Hi after reading this site for a couple of months i finally bought a 2001 3.0 gold x5 i had her looked over by the local dealer and an indy and had a manageable
list of repairs to haggle over with the seller.Closed the deal and drove off yeah..
an hour or so later i filled the gas tank and headed home what a nice car.........
next morning my new car has a pool of gas under her.grrrrrrrrrrr.I removed the back seat and finaly locate leak at rear pasenger vent fitting on tank . I ordered a new tank and will begin dismantling her .I hope my luck improves ...is the tank a common failure on this car ? I did a search but did not turn up much..
cheers Rondo
