Foretravel's shop manual for techs said 25 years ago at some part in repairs to use a "KGP"

Known good part.

In other works out of your spare good complete system you swap parts until you have an "aha" moment.

Tell me how else you could diagnois the system.  I rebuild entire off road motorcycle engines to restore the power and for sure to cover the "aha" issues that are inevitable in a mechanical device after use.

Low volume production modified every few years twenty year old complicated systems are not easy. Previous repairs, poor fluid/filter replacement, different wear from different weather area use would make every service repair different from the last.

Add new techs to the mix.  "Never seen that one before" stuff.

So how far do you let someone who has no clue what the route cause of the problem is go replacing parts? Engine won't start hey, just replace the starter, batteries and starter solenoid that should take care of it. How about this. I bring my big truck to a repair facility and ask them to replace my failed boost sensor. They come back and tell me the computer is bad and they want to replace it. I insist on a new boost sensor, guess what fixed the problem. Why could not the reputable shop diagnose a bad boost sensor. Want another example of not getting to route cause before replacing parts? I have volumes, all personal experience. If you can only diagnose by replacing with KGP then you should be doing something else. My Opinion.

My spell check changed point to part.  After enough troubleshooting and expert repair and no joy was when Foretravel allowed the shop to take parts off of new coaches in stock to help fix a customers coach. Multiple subtle issues sometimes

Fuel, air & oil hoses suffer with age (end of life cycle) related issues. 
Most of the time they simply leak and (occasionally) collapse internally.
The action between the fitting and the (interior) lining of the hose needs checking. 

Within a hydraulic system (most of the time) the high pressure hose is the problem. 

At an earlier point in time, replacing hose was easy.  Nowadays you will not be able to do anything (unless you do it for your own personal use btw) except replace the entire assembly (new fittings & hose).

It's a legal thing..  pc

NOT AT ALL
If you have the where with all, go for it. 
In my case, the lawyers have gotten into everything in the repair business.  On my own personal stuff I replace hoses without issue.  Repairs to a customers rig has gotten to the point that there is more than financial issues at hand and I'm not interested in dealing with lawyers (for anything.) 

Most do not have the proper tools to replace hoses anymore and the industry has almost phased out rebuildable large fitting (in my end of the woods anyway.)  PC

So no more aero-quip stuff.  Parts switching only.  No rebuilds.  Expensive

I have been out of pocket for awhile, building a new house. I really worry about FOT, reading this thread makes me sad that they have not educated there techs. I short hydraulic school will save them and there customer a huge amount of bucks. The tools for this whole process is 4 or 5 hundred dollars. These are Avery very basic system. Gear pumps last along time unless run dry. Motors don't. I'm surprised if no proper tools they didn't remove 1 fan motor out see how works then switch. I would fight for a huge discount on the fan kit. I deal with very complex RR equipment I would get a huge reprimand for the diagnosis on something so simple.
Good luck
