You say the guy from the pump shop "speaks from experience." Does that mean he's seen your machine and heard it run? I was lucky enough to work in two pump shops at two Deere tractor dealerships - so we usually had the trouble machines on site. As far as diaganosing over the phone with only an injection pump in you hands? That's pretty hard to do - and some pump guys (not all) are clueless when it comes to the rest of the tractor, truck, or whatever. Not all diesel pump bench technicians are diesel mechanics.
I still haven't heard what model pump you are speaking about, and mounted on what equipment? And, what part of the pump did the pump guy tell you would work better with a sulfur additive? You seem to be taking offense - but I find it equally offensive being told something - that I have 40 years experience with - that ostensibly makes NO sense - not to me, anwyay. It's no secret that low-lube diesel fuel can cause premature wear. In a pickup-truck, it might mean the pump has trouble after 100K miles instead of 175K miles - the low-lube causes excess wear over time. Advance-timing parts, transer pump blades, sometimes some chipping on the cam ring, etc. But - you have stated that your pump ran bad on pump fuel, then got better again with an additive.
So, I ask again - what pump, what machine, and what part of the pump is your "experienced" pump guy telling you is the culprit?
I am also aware of the problems with colored fuel and dye sensors in newer, electronically controlled pumps - but I assume that is a totally different issue - considering this is an antique tractor forum.
In regard to the posts about differences in highway and farm-dyed diesel - it must be a regional thing. I'm in central New York - and our farm-fuel is high sulfur and comes out of the same tank as the home heating oil - right at the Port of Albany. The highway, low-sulur diesel comes from a different tank at the Port. I've read, that in a few years - things will be different - but I'm talking about now.
Also - another poster mentioned a flood of Standayne pump-seal problems with Deere stuff, early 90s with pump fuel? I was there, working for Deere and working on injection pumps, I never experienced it. Deere uses the C, DB, JDB, DB2, and DM4 from Stanadyne-Roosamaster - and we always had problems with certain plastic internal parts with ANY fuel - farm or pump. But seals? Other than normal wear, I never saw it.
