hi to all. could someone please tell me where the fuel filter is located on my 86 E190 2.3, and if there is any special procedure to swappin it out correctly? this car is new to me and i can't get a haynes or equivalent manual to service it myself yet...something i must do very soon when i have the $$$. the car is really in good shape, but sat for a while, and i'm sure i can eliminate some of my idle /running issues by changing out the fuel and air filters. also, is there a brand preference for the filter that must be used? thx in advance for any help/suggestions.
