Kubota b2400 question

[Iron Brew]

I have a b2400 with a loader. The spool for the loader is labelled

in, out, a,b,c,d and DFP.

To me, all self explanatory, except for DFP. There is a line coming out of the DFP position which runs to the rear of the tractor. This line is showing signs of damage, so I'd like to replace it. As such, I have three questions.

What the heck is DFP?

What size/type of fittings does Kubota use? I've tried a couple, and don't seem to be able to match. Next step is to take the spool off and take it to the hydraulic shop, which I'd rather not do.

In the same position as the DFP, but other side of the spool, is a plug. What is this spot for? It has no label.

Thanks

Rod

My B2400 (2001 I think) has a Husco valve, and I think the ports are all 3/8" O Ring Boss (-6 ORB). The work ports (a-d) have adapters to make them 3/8" NPT male. The power and exhaust ports have adapters to make them -6 JIC male, I think.

DFP must mean power beyond, based on your explanation of the other two ports ("In" and "Out"). Mine is labeled "PB". This line probably runs to either the hydraulic system manifold block beneath your right foot rest or to rear remote outlets or a backhoe if you have them.

Why not just take the line to a hydraulic shop and let them replace it?

Main reason actually is... it is winter here, had a bunch of nasty weather, and always a possibility of more... if I can get the parts, and swap it in right away, that would mean no downtime... I seem to find problems when I try to do things like take a part in to get a new one...

I'll see if the nearest 'bota dealer is open tomorrow... Would rather get it from the local hydraulic shop, but... small town, knowing my luck I'd pull it off, and there wouldn't be parts available until... and I'd find a way to break the weak link... I know I would...
