I finally got my fuel system upgraded. MBZ covers the fuel lines, a new fuel pump and the labor to do all that crap. My cost is the fuel filter and the regular labor to install the fuel filter. This is for a 98 ML which was deliverd in Oct 97. Not bad for me since the truck is nearly 7 years old but with only 60k miles. It has been more reliable than when it was new. Hope to keep it for another 5 years before dumping it, will keep my fingers crossed.
