I'm kind of wondering why you are using the low-sulfur stuff - since farm and off-road fuel will still be around for a few years yet.
I don't believe the story about low-sulfur causing the problem. I also doubt pump shop people know the cause. They can suspect certain things, hear rumors, read conflicting service bulletins - just like anybody else. I worked in a pump shop back in the late 70s when Stanadyne pumps were failing often in GM diesels. I heard an awful lot of possible reasons given - by General Motors, Standyne Corp., etc. The truth is - a guy in the pump shop does not necessarily know more than anybody else as to what causes a problem in a pump unless it is overt.
This I do know. Now that ultra-low sulfur diesel is " hydro-cooked" to get the sulfur out - many additives are put in to bring the lube-quality up afterwards. It is possible that some of those additives are the "straw that breaks the camel's back" with older o-rings and seals. This also happens with bio-fuel - very often. Even eats up old fuel lines.
In regard to your CAV pumps? If they are rotaries, and they are leaking at the back of the pump - they do NOT have to come off the tractor. It's a 15 minute fix. On the back is an end-cap that's held on by four screws or small bolts. It is the regulator and wear-plate for a low-pressure, vane fuel pump in the pump. All that needs to be done - is you take the scews off, pull the cap off, put a new o-ring in, and put back together. Easy to do - no adjustments get changed. We had many brand new John Deere tractors - especially the 2940s - that we had to pull those plates off and fix before they even got sold. Now - if the leak is somewhere else? Different story.
