In Canada the high pressure pump is $3400 and the ECU is $2750!
No, I don't think your dealer will have them in stock!! In the case of a ECU you have to email the SN of the tractor and engine to Kubota so they can program it to match your tractor.
It could be. I'm going to drain and flush the tank and clean all fuel lines to the UP pump. If I still do not get and spray out of the HP pump then I will pull the pump to understand why it's not working it's a mechanical pump so should be pretty straight forward. The ECU that controls the suction valve has not entirely left my line of sight.......I haven't found a service center yet that understands this assembly to any extensive amount.
There is a mod for early, 2011-2017 or so SuperDuty's. The short version is you wire a rheostat into an upfitter switch and get a high idle. My understanding is newer SD's have an auto shut down after x amount of idle minutes. The moral is don't idle engines with DPF.
Did you by chance save the gunk from your water separator? I am thinking if you could determine if it dissolves with heat and nothing was left it would help to reassure you that you had only one clogging material, not two.
one of the halves appears to have the oil filler pipe running through the middle My thought that you could suck out the fuel through the fuel filler pipe won't get the fuel from the left half due to the check valve. - So the Gelled fuel was just that and did dissolve very easily with minimal heat.Did you by chance save the gunk from your water separator?

Second, did you replace the fuel filter or just warm it up? If the filter itself is passing less than the normal amount it could cause problems. That would be an easy thing to do if you haven't done already. It looks to me on the parts diagram that the bleeder screw would allow fuel to leak out from a line that has a T in it, making some of your previous experiments harder to interpret.
I am clutching at straws here on your behalf because draining the fuel tank could be easier said than done. It is in two halves connected by a large tube with a check valve in it
After looking at the parts diagrams and comparing with the diagram from the wsm, there are a lot of discrepancies. The order of the components is not exactly the same. My parts diagram is several years old, so you need to download the one for yours. I am curious about the function, and so as not to hijack your thread, if I get ambitious I will start another.
Edit: I have looked at the kubota online parts diagrams, and there has been no changes since I printed mine, and the 4060hst is identical to the l3560hst.
Oh I agree that's not the cleanest practice. I recall the fuel flows from the center in and then out through the outer side holes of the filter to the HP pump. so when you fill a filter you are filling the center directly you would have to work at it a bit to fill through the outer row of holes which would be the only unfiltered fuel.(unless I have that backwards) In my case the tractor was dead and after putting fresh fuel in the filter that never had any sign of jelling I have since flushed the entire system of the "old" fuel and installed all new filters and fuel. There would more likely be crap in the lines from my troubleshooting and taking everything apart than from the new road quality fuel I poured into the filter.
