I read in a few posts back about the fuel hoses on the top of the tank rotting. How could I troubleshoot this problem? I can smell gasoline in the car and around the tank. Any help is greatly appreciated.

There's a metal or plastic shield right behind the L/R tire covering the hoses to the gas tank.<br>Pull it off and use a flashlight to view the hoses and venting tubes. The rubber hoses can dry-rot right off the tubing, or the tubes rust at the top of the tank, or both if you're a special person. The cover should have 3 or so 8mm headed body screws that BMW loves to use.

These tubes can be replaced but you need to lower the gas tank. Drain (or drive safely) the gas tank before lowering it.<br>You can use any aftermarket gaslines at part stores. Bring the old tubes along.<br>That's what I did.<br>CN<p><br><i>: There's a metal or plastic shield right behind the L/R tire covering the hoses to the gas tank.<br>: Pull it off and use a flashlight to view the hoses and venting tubes.

of the gas tank that are brazed/welded onto the tank. Trying to reweld new ones onto a rusty tank isn't a sound/safe idea. Are you talking about replacing the rubber hoses that are running to the metal tubes?
