Brought in for first service to dealer at 12,000 miles, my local mechanic told me having hard time getting fuel filters. While at shop they tell me truck ready and tell me since they don't have the rear inline fuel filter they did not put the second that is next engine either since it suggested they be replaced at same time, I ask parts desk about same they tell me they don't have a clue when they will have , my deal is what I need to maintain warranty besides keep up PM on my new rig, I have always prescribed yo take care of your tools and equipment and they will take care of you, I would dearly appreciate any thought on this, thanks in advance
