I don't know why I have never run across a varnished up diesel system... and I've worked on plenty of old junk before. You can't pin the pump? Don't think I've ever run across a Bosh that can't be pinned. Want to know how to take a reasonably price pump rebuild and make it stupid expensive? Pliers and vice grips. Then don't realize you are missing shims and throw it back together. Depending where you are at, you might want to talk to Area Diesel as a second source. I still cross check my shops no matter how long I've worked with them. Every once in a while we all learn something.
