Hi Brent welcome to The Diesel Page!!Originally Posted by BR455
Since you are a newbie why not tell us about your troubles and see if we can help you with the DS-4 first before you go through all the hassel and head aches of converting to an DB-2. DB-2 have shorter usefull life I have been told. I have over 175,00 miles on my current DS-4 pump. Is that good life? I think so. Now I'm not saying there are not some problems,but many people have tried different fixes with mixed results. Tell us your trucks story!
