Don't know what all warranty work you need done, but as far as the lift pump many folks just go to Cummins and pay the $140 or so bucks and do it themselves. The advantages are 1) you know the work is done right 2) you get none of the 5 Star hassle ("your psi falls in spec", " it is not covered by the warranty", "Your truck has an aftermarket 'performance item' so we need to void your warranty", etc... )
