I am going to look a t a 2001 2 wheel dr 3500 HO . My question is what to look for on this truck ??? It only has 6700 miles on it. And also If I buy it I would put guages on it . But do you put the fuel pressure guage under the hood or on the pillar mount?? And if I put just injectors and a after market air filter and a bigger exaust will that be a notticiable change??? Just many Questions As you can see I have a first gen so big step here. Thanks
