I am new to the cummins world. Just purchased an 02' quad cab 2500 4x4 with 66,000 miles. I've had it for 3 months and I love it. I have a question I just bought a mechanical boost guage, and electrical EGT and fuel pressure guage, I hear the presure guage is very important. Just wondering where to hook up the pressure sender for the pressure guage and the best spot to hook up the boost guage. I was told the intake plenum. Any help would be great.
