I'd like to hear more details. What engine, what type and vintage of pump, and what parts specifically failed?
I worked in a pump shop - dealing mostly with Roosamaster/Stanadyne and CAV pumps - and you've got me stumped. Pre-1986 built Stanadyne D series are known for the plastic weight retainer falling apart - it's a vibration dampener for the governor weights. The problem has nothing to do with lubricosity - although the presence of alcohol or water in fuel has been blamed for shortening its life. Stanadyne changed the type of plastic in the ring three times before giving up on it and going over to the EID instead.
The older Stanadyne/Roosamaster C series often had problems with the rack and pinion gears wearing out in the governor/throttle - but again it has nothing to do with low lube.
I have never experienced a situation such as you describe - where low lube fuel somehow screws up the governor and then adding lube later corrects it. Please elaborate.
I have seen accelerated overall parts wear - over time - with very thin fuels. Our military had, and still has miserable problems with pump failures in Iraq with GM 6.2 and 6.5 diesels - but that's a totally different story - much due to using A1 Russian tank fuel and high heat. But, the failures they are having - are permanent - they don't self-correct by adding sulfur or lube.
I realize that you haven't mentioned what make of pump. Stanadyne is the orignal and the rest are licensed copies (except for AMBAC). I own two machines with AMBAC rotary pumps (AC HD6s), 18 trucks with Stanadyne DB2 rotary pumps, 2 Volkswagen Jetta diesels with Bosch VE rotary pumps, 2 Chevy Chevette diesels with Diesel Kiki VE-type rotary pumps, and an 85 Isuzu P'UP diesel truck with a diesel Kiki rotary pump. Also a few Deere, Case, IH, Ford and AC tractors with Roosamaster/Stanadyne DB rotary pumps. They've all had pump fuel run through them and not one has had the sort of problem you've describe.

On the Road with Dave Gohl: Deere Departed Friend - by Dave Gohl. Have you ever had to part with a dear friend? It's not easy. If it's due to death, your feelings could be in disarray for days, months or even years. Even now after almost 4 years, I still miss my dad. I remember when I was a kid my dad sometimes would tuck my brother and I in at night and we would ask him questions about his childhood on the farm. To this day, it's some of the best stories I've ever heard. And now, I'm so glad that I asked those questions, and if I were a little smarter i
