What I don't understand is the price difference in getting a JDB pump from a 4020 done as compared to the DB2 pump from a Chevy or Ford truck? They are all Roosamaster/Stanadyne pumps, takes the same time and labor to take them apart and put back together, parts cost the same, yet I can buy rebuilt Roosamaster pumps for 6.2 Chevys or 6.9 Fords for $275-$325. In regard to the plastic governor weight retainer ring, it can be completely eliminated if desired for an extra $45 with an OEM Rooasmaster/Stanadyne part as used in the DB2s. Also, in regard to dealers doing the work themselves at one time. I worked for several dealers where we did our own pump work - sometimes in the shop and sometimes out in the field if necessary. The JDB, DB, C, or CB pump can be pulled apart and put back together in one hour. If it has to be mounted on a test-stand and adjusted and performance checked, it all takes much longer. But, many pumps, especially the DBs or JDBs have nothing wrong with them except for the shattered plastic ring and a blown out regulator stop. One hour's work (not including removal and reinstallation) and $35 in parts certainly beats spending $500 if it's not necessary. In regard to the pencil injectors, they are not rebuildable. At best, they can be cleaned, the seats lapped a bit, and the pressure checked and/or set - but that's it. They won't last anywhere near as long as a new one. Unlike the full size injectors, the individual parts are not replaceble.
