Was hoping somebody had prior experince with where the hydraulic filter housing tube enteres the reservior pipe on the frame of the tractor circled in pic.Is the pipe a tight fit into the reservior or is there a seal there?Mine appears to be dripping fluid.Thanks

curious, found the diagram,zooooomed it up.
There appears to be TWO O-rings, #150, probably need to replace BOTH of them.
Looks like you have to remove a LOT of 'plumbing' to get to them,so have a box of bandaids close by !!
I like to print off 2 copies of the diagram,zoomed up of course. Use magnets to hold them close by .

Wow you found it.Thank you so much.Kubota oil is more expensive then a bar of gold these days.I read a coiuple of threads where they couldn't figure out why their hydraulic filter was still leaking and I bet it was those orings.This will be the 4th time I will have had to remove the fluid as I had to flush all the lines.Not looking forward to removing those lines going to the front pump.Thank you again
