I'm reworking the connections on my propane tank and I need to replace the rubber hose that connects the bulkhead connector at the bottom of the compartment to the tee fitting where the copper line for my fridge is connected. I need a longer, 2 foot hose with a 3/8" male NPT on the end that connects to the tee (same size connection as the output of my 2-stage regulator) and a 5/8" flare swivel to connect to the bulkhead connector.

Most of the hoses I see online use a 1/2" flare swivel on the coach end. Does anybody have a good online source for propane hoses? I'm not sure I have a local supplier.
 
Christo,
Try the local LP suppliers for a source. Mine gave me a name and that company would not deal with me even as a business. So, I did what I often do with special hoses... I got the ends out of the hose I had and took them to a local hose shop and said I need a piece of Low pressure LP hose X-long between these. They cut a piece of some kind of hose (Aeoquip I think) and put the fittings in and swaged clamps on them.

I'm trying to picture what you started with (what this hose connects). My coach has no rubber in the propane path, and that's generally how I tried to to my Airstreams as well. All lines are hard lines until you get to the point of use where it's a metal flex hose. I do have a rubber hose to connect accessories (portable heater, external grill, external propane supply tank), but I like the added durability of a braided stainless sheath. With creative search terms, I've had luck finding almost everything I needed on Amazon, though I do remember sourcing a couple adapters/connections at the local farm store.

My general rule when I can't find answers is: go to the local source (a non-chain, local supplier) and look for the oldest guy there. He's usually got the answers.

I believe this is the OEM setup:

Christo,
I am not sure what the Kid thinks would be a good hard line there and I would really like to see it done in black pipe with unions and couplings. Soft copper might be more practical but it would be susceptible to fatigue failure. It would take much difference in the natural frequency of both ends to make that happen.
If the hose you can find has a 1/2SAE flare swivel on one end, just put a male adapter at one end and be on your way safely.

Little bit of a hijack here but I'm trying to restore my propane setup. Could someone tell me about or show me their connection beneath the bulkhead fitting? I have a 26' model and it looks like there was some kind of line from the bulkhead, forward into the wheel well, up and over the contents of the wheel well and then down again to a 5/8 male flare fitting hard line at the forward end of the well. That line then crosses from right side to left above the aux fuel tank and is reduced to 3/8 flare before going up into the galley.

My current issue is from the bottom of the bulkhead fitting to the next flare connector. What should be there, how is is routed, what is it made of?
 
Matthew,
I suggest that you make contact with the Sunshine Statesmen. There are lots of coaches in Florida that you can look at. I would tell you what is in Chaumière, but she is 23 and a lot is different.

I see a lot of standard flared copper tubing on my coach, looks original.
 
Thanks for the feedback, I had a look at the Sunshine Statesmen website. To provide a little more detail to my question, see the photos I've attached. In the photos of the right-side wheel well, you can see a distinct paint/undercoating holiday line where something used to be and I'm operating under the impression that I need to put a copper line back into the same location. Can someone confirm or otherwise? it appears to be 1/2 copper with 5/8 flare fittings. Luckily, no one has installed any compression fittings in the propane circuits.

You can see where I've installed the propane tank, new regulator, quick connect fitting, and installed a new bulkhead fitting. The PO took out a decent amount of the propane stuff so I'm remaking it.

@tmsnyder No I hadn't called either of the Jims to check on this item. I presumed this was something that had to be made unless salvaged from another 26 footer. I'm nearish to JimB too, approx 1-2 hours.

I had considered having a thermoplastic line made for me but felt like it was probably supposed to be copper.
 
Matt,

Your first picture is a modified system with a two stage regulator and a disconnect that is probably for the RV-que. In a 73 all the water and LP lines were soft copper. I am sure that all the LP lines were 3/8 and flared. Where the line runs through the right side wheel well it is covered in a protector. Chaumière only has LP to the coach heat and the range. Neither the water heater or the reefer use LP.

Matt
 
@Matt Colie Yes, I've just removed the original-looking, Progressive Dynamics, single stage regulator and replaced it with a dual stage. I've added the quick disconnect fitting, like you said, for an external appliance such as an an rv-que or the like.

My coach is impressively original and unmodified but I couldn't swear on these 5/8 flare fittings being original. The copper surely has a nice patina but it doesn't take nearly 50 years to look that way. It could've been oversized a decade ago and it wouldn't be shiny. If they are original though, then adapters would've been needed to take that down to using a 3/8 ID line between them.
 
On my '78 the propane line from tank to fridge runs above the wheel well. Helps avoid tire damage hitting a propane line.

In the future I'll replace rubber lines with copper.
