L245DT leaking fuel under middle delivery valve holder

[North Idaho Wolfman]

Thanks! I'm bit nervous because I haven't done this before but I hope I can do it. I have access to a decent torque wrench, any idea what is the torque spec for those holders?

There is no referenced torque values for that pump in that model.
This is what it has to say about this in the manual.

This is the referenced values from a newer pump, it is a very similar pump and you could safely use these values.

Update:

I just finished fixing this.

There was an o-ring on each delivery valve holder. The o-ring had a slight blue paint strip on top so I'm pretty sure it came from factory like this.

The o-rings were all hardened and cracked so i replaced them with 14x2.5mm o-rings. I also replaced the copper seals with kubota original parts (part number 15221-51240)

I torqued delivery valve holders to 42nm (as I'm from Europe )
No more leaks so far and it was pretty easy job even for a novice like me. I took care of cleanliness though.

Thank you everybody for good advice.
