This is something many owner's and mechanics miss. That little check valve on the side of the injection pump can cause a lot of starting problems on the older diesels.

PLEASE NOTE: UPS Ground shipping only to the lower 48 states. Sorry no international. Even though this is a synthetic fluid it should be changed on high mileage wagons. I think some owners figure it will last forever.
Oil filter changes are important, but I believe on these high interval oil change schedules that changing the oil fitler can be just as important! Use the wrong filter and the engine can suffer serious damage.

From my experience the only thing that goes wrong with the front seat back pockets is the top bungie cord that holds the net up wears out (loses its “spring”) and sags badly. When was the last time you saw a 1973 to early 1990's seat back netting that was NOT sagging???

With this kit you will be able to hook up a pressure gauge to your intake manifold and route it inside your car for the purpose of monitoring your turbo charger boost pressure while driving.

This is an original first aid kit. It came out of a 1981 300D. Contents look mostly complete and are original. I have 2 so it may or may not exactly have everythings inside as shown below. It probably should not be used as a first aid kit. This should be for original cosmetic purposes only.
