84 300dt crazyness
The issue im running into with the car is when i park on an incline with the front sitting higher than the rear the car wont start, i have to primer the system to get it to start. When i park on the incline with the rear sitting higher than the front it cranks right up without having to primer the system. i doubt there is air anywhere in the system cause it runs great when cranked. is this normal? it wasnt doing this when i first got it on tuesday, i tuned it up with new fuel filters, air filter, belts, oil/filter.

You said it only does it at an incline, and after you changed the fuel filters. I would double check the fuel connections: re-tighten the primary spin-on filter, and re-check clamps on the pre-filter and all fuel lines. You could have cracked any one of your fuel hoses, just by moving them (I'm speaking from experience). If the hoses are old they might not stay primed. It could be very hard to determine if there are any leaks just my looking at them. They will fool you. If you don't know how old your fuel hoses are (cigar hose, fuel hoses to/from the tank, and bypass injector hoses), you should replace them. They are fairly cheap to replace and well worth the piece of mind. If this doesn't help, I would look next at your fuel tank strainer. Good luck!

I usually go to pelicanparts.com (peachparts) or mercedessource.com. Dieselgiant.com is another.
Kudos for having the same car. Mine is blue/green in color, which I've not seen many with that color.
