Okay, I'm swapping a db2 onto my 95 k2500 and need a little help with db2 info. First off, is there a site I could read up on tuning pumps? On the more practical side, there are two electrical connections on my 2829 pump, I'm guessing they're for fuel shutoff? Which is hot and which is ground? And will ds4 injectors run ok on a db2 system? Thanks in advance!
