No complaints with their service department, other than they do not have a field truck to at least come out and do minor in the field repairs. For the fuel leak, when I brought it in the second time, they even did the repair with the tractor on the trailer. I was taking the tractor to our north farm up in Missouri the next day, and they did a temp fix to get me up and going until the replacement part came in.
My experience with their sales and parts department has not been the best, which is why I ended up buying my tractor from Straub in Wichita. They seem to be either understaffed or a little disorganized in the parts and sales area.

Pretty much all tractors use a small piece of hose in the suction line connecting the two pieces. And they do not normally create a leaking issue, after all they are on the suction side. I've seen loose ones suck air into the system, but generally they do not drip oil unless the hose is cut or deteriorated.
Does it only leak when the backhoe is hooked up? I am wondering if you could have a plumbing issue of some sorts when the backhoe is hooked up and causing pressure to build up in the suction side. If not, a close inspection of the hose and the pipes should reveal some sort of a flaw.
Some of those fuel lines you mentioned gave us fits. A good fix is to just remove the factory braded hoses from the banjo fittings and clamp on some good ole' USA hose. You have to cut the crimp, but that is easy.

It leaks when I engage the rear hydraulics by pushing the lever that is up by the seat. Nothing is hooked up to the rear hydraulics at this time. It is a brand new hose and the pipe seems fine, I have checked it from front to back. There does not appear to be any damage to it.

If you engage the hydraulic remote with nothing attached to those ports, it forces the oil to go into a bypass situation as the oil has no where to go. You may notice the engine rpm drop a little also. You are loading up the pump on this open center system and causing backpressure where there should be none. So your suction line is holding some pressure and leaking. Momentary bypasses are normal and frequent, like every time you curl your bucket all the way to a stop you have a half second of bypass. But if you engage the remote and leave it engaged for a bit, you will have problems.
I think it is J.J that is so good at hydraulics, perhaps he will contribute.
Is this similar to the hose you are talking about.(The suction hose from transmission screen before the pump)Or am I not understanding you correctly and it is a line from your aux valves.
As I am not familiar w/ the 35 series this is a pic from a 30 series and they very well may be completely different
If it is building presure in your transmission then I would think the tranny is not venting properly.(Plugged or frozen vent)

Thanks, that makes sense.
I did have the backhoe hooked to the hydraulics originally, when I attempted to use the legs to lift it into position they would not lift under the weight of the backhoe and that is when I discovered the leak. The legs and arm and bucket all work, just not under pressure. When I replaced the hose, I did not attempt to reconnect the backhoe and just moved the lever by the seat to check my work. So I have probably held it for 4-5 seconds and then the leak occurs again. I will hook the hydraulics up to the backhoe and see if the leak continues. Maybe it is fixed and I just do not know it.
