Joe, to answer your comment on air getting in thru cracks on fuel lines at fittings why not do what I did to them many years ago when this issue was first mentioned. I had cut a hole in the floor right above the tank and were pickup fuel lines are just to see wether I was going to have a problem with this issue too. I did find some small fine cracks but not causing an issue then, so, to make sure it was not going to happen I put some good polyurethane caulking on the hose and spread it around the hose to "fill" the cracks and seal them from allowing air to enter. Fast track to a couple of months ago when I decided to replace them finally and noticed that the cracks had actually got a bit wider "but the caulk was still in perfect condition and had expanded with the crack and still sealing. So the motto here is "if you can reach any problem lines just smother caulk around them and let it set and you will be able to put off the obvious till it suits you".
It  worked for me by the looks of it. Anyway it is a simple job to do and very little or no cost fix.

Final update,

the shop (Oregon Motorcoach) voluntarily removed the labor charges from the fuel line air purge and just charged the labor for the fabrication of a bracket and installation of the priming fuel filter block.

It was still more costly than I had anticipated. (Isn't that always the case?)
But there was no way for me to have done a DIY on the fuel lines. So we are good with that.

In the end. We will be pushing up Daisies before the fuel lines will need redoing. Heck, in 20 years this coach will be pushing up Daisies.😁

I'm willing to bet the coach will still be around in twenty years. Make a great house for some one. Diesel will cost too much to drive. That is not good.

Well, it's the end of our sixth day at OMC.
So, they have been unable to clear the air from the fuel lines. After SIX HOURS of labor @ $125/hr trying to purge the lines. They come and tell me that for some reason someone in the past removed the the first fuel filter block with the primer pump and replaced it with a unit that doesn't have a primer/purge pump. ????WTF over.

Even more puzzling and quite maddening was the fact that they saw this when hooking up the new fuel lines at the primary filter and didn't immediately stop and suggest a quick and easy swap to a filter with the pump. Instead they only told me that a new filter/primer pump should be installed after expending $750 of my money on a futile exercise and running my starter way too much.

We purchased our U320 a little over 2 years ago.  It checked out perfectly, so said the commercial airline pilot we purchased it from.
We found that after the RV sat a few days, it would fire up and die after a few seconds.  Sometimes, it would go ahead and fire after staying on the starter longer than desired.  We also discovered a lot more issues the airline pilot failed to disclose.  Like the AH and a parasitic draw, and the many other nagging issues that comes with age.

So it goes to the RV shop.  I had called to discuss with the Service Writer what I was finding, we schedule a time so that it could "get right in and out".    After finally getting the RV back and a list of things they were not capable of repairing, it goes to a Truck & RV repair shop.  After a couple of more months, we get it back to find, most of what we had paid for at both shops were not done well if at all.

One of the "repairs" was to replace the fuel filter primary priming unit with a pass through, similar to your experience.  That part is now on the shelf and the proper priming filter housing was installed.  I can certainly understand BigDogs pain.

It seems to be easy to find a shop willing to not do the right thing.  I've paid for several lessons and ouch.

BKW,

When you purchase a used coach, don't expect the PO to be able to disclose everything. Air in the line is rarely a sudden development and usually happens over time as the components age. The hard starting may have just started to show itself or the PO may have just gotten used to it. The front door of our house sticks when it rains but I would never think to disclose that to anyone. Do a thorough inspection but then expect to have to fix or replace some items when you purchase a used coach.

BKW,

You might consider starting a new topic about your coach issues. Many knowledgeable & experienced folks will be along shortly to help you out with sage advice and some cold hard truth about the cost of feeding our glamping habit.

It does get better once you fix the stuff that the prior owner neglected. And these are old machines. They are very well built. But they are still old man made complex machines subject to wearing out.
