Separate issue since the car is new to you, buy and store in the trunk: both fuel filters (2 sets), 3' of return fuel line, wrenches, cutter, pliers and screw drivers to install the filters and return line. Also, you may need to be able to crack the injector hard lines at the injector. Add some shop rags. Buy a small inexpensive storage box (small fishing tackle boxes work) in which to store everything.

NAPA has a 1/8" fuel line that is locally available and seems to hold up better than the covered line available from MBZ parts suppliers.

Be sure that the filters are changed before taking a long trip.
