Leaking Propane Hoses to Regulator

[Wayfinder]

Sorry if this is duplicate, but I cannot find the correct search term(s) in this forum to find the right thread.

It's time to replace my original propane regulator-to-tank hoses.  They are leaking at the metal seams.  

Since my rig is a 2016 (#110) would you recommend also replacing the regulator too?  I see no problem with it, yet, but, you know how that goes.

Also, what type of hose upgrades might you recommend, if any?  Are braided more flexible, safer, better?  A little longer than original or not.  I used a string to measure mine, I'm not sure how they measure them, but it looks like they may be nearly 15 inches (or 1 1/4') on E-Trailer.com.  Also looks like they have the inverted flare male connector (the smaller diameter one).  

Any part(s) suggestions are welcome.  I'm okay with making it better than factory-provided.  

Is there anything that will allow for less movement of the hoses when taking the tanks in and out?

Here's what I see so far: https://www.etrailer.com/Propane-Fittings/JR-Products/37207-30725.html

 

When it's warming, I intend on checking all the lines under the hull too for potential leaks.

 

Happy New Year (2023)

Pretty common for those pigtails to fail with age. I wouldn't bother replacing the regulator if it's functioning correctly.

You could replace the regulator and carry the old one as a back up.

Just stick with the same length and style in a quality brand hose. The e-trailer cheaper MB Sturgis hose is made by MB Sturgis, not just a repackage like the JR and Camco. Hoses with the stainless steel overbraid won't do anything for you in a protected tank enclosure except cost more money.

Or, keep using the old working regulator and carry a new one as backup.

Carrying too many spare parts gets really expensive. Not only takes up more space, but then I need to upgrade from a 1500 to a 2500 truck. Oooh, that's a good reason. LOL

That’s the idea….

You’re on to something now! 👍🏻😊

Getting a new regulator will make you feel good for being on the ball. Getting a new truck will put a smile on your face every time you have to go somewhere, or even look out in the driveway. 😉

For what its worth - last Spring I replaced my hoses with two of THESE in the 12 inch length combined with two of THESE emergency gas cut off devices.  All was purchased from TechnoRV.com.

A couple of notes -

1 - make sure that you check the size of the connections on the hoses.  Given your hull # I'd bet that you will need adaptors for these hoses to connect to the regulator.

2 - Given that the fittings on any of these hoses are made of brass, be careful that you do not over-tighten the fittings in that you stand a good chance of stripping the threads on that relatively soft brass.  I believe that the torque setting is 25 foot pounds (but please reconfirm this).  

3 - Make certain that you use "gas" tape or pipe dope.  The tape is a bright yellow color and the pipe dope will be clearly marked as for use with gas.

Well, that's a huge cost difference when I'm already looking pretty good, AND I have the Decked system already in the truck.  LOL  But, if I do more mountain-driving, then I'm sure I'll change my tune. 😝

Bill, 

Looks like I already have the hose connector adaptors.

It seems to me that the brass 90 built into the 12" replacement hoses you bought would reduce the stress on the hose connections, likely increasing the useful life of the assembly.  Does anyone know why Oliver doesn't install 12" hoses with the brass 90's, instead of the longer hoses that must be bent into a tight curve to make that 90-degree turn from the tank to the regulator connection?

That's an awesome looking rig you have there. I saw in your signature line that you already have a new truck that's pretty awesome but it still sounded funny saying it. Love the decked system. I've seen that on some YouTube RV channels and looks like a great way to organize gear in the bed and still be able to get to everything.

I was thinking the same thing. The short hoses with the 90 deg fitting are obviously designed with this in mind.

And getting a truck big enough to haul everything will get you admitted to the cool kids club.

Yes, I thought the same thing.  But, the original hoses did give me more "wiggle" room - particularly when taking the tanks in and out for refilling.  Having said this, I'd still do the same thing over again in that the new hoses really do reduce that big bend in the original and clean up the space a bit.

I recently replaced my aging rubber hoses with some stainless steel braided hoses that had pressure gauges on them.  https://www.amazon.com/dp/B07ZCRFLHD?psc=1&ref=ppx_yo2ov_dt_b_product_details   In order to eliminate the acute angle of the hose run, I turned each of the tanks' connections "outwards" on the trailer about 30° which made for a nice smooth curve of the hose.  Be sure to always have a bottle of propane gas leak detector with you to confirm no leaks every time you connect your hoses to the tanks.  https://www.amazon.com/Camco-Gas-Leak-Detector-Dauber/dp/B0006JLSMO/ref=sr_1_6?keywords=propane+leak+detector+fluid&qid=1672186001&sr=8-6

I installed brass 90 deg “street elbows” with new short rubber hoses. One important part of inspecting the hoses is to look for cracks (weather checking) and stainless wrapped hoses prevent this. Plus they are completely unnecessary in this application.

Be aware that the small check valves must be retained, they provide one way flow away from the regulator, otherwise the switch over function will no longer work, since the tanks will essentially be connected to each other.

When I get the new lines installed, I'll upload a before/after pic.  I too am hoping the new shorter lines with 90 degree connectors will reduce movement when removing tanks.

[Wayfinder]

Well, these new hoses went on in a snap.  No leaks now.  I did need to rotate the tanks 90 degrees so the lines fit best.  We'll see if they last another six years.

[ScubaRx]

Very nice setup, our unit was built in late 2013 and may well be in poor shape. I will check the hoses out tomorrow.

Wayfinder,

Nice job on the replacements gas lines! I always like a really clean looking fit and finish. It’s all in the little details for sure! 👍🏻

You can leave the plastic cover off all the time, it is a rain shield and completely open at the bottom. It isn’t needed in an Ollie. That way you can inspect the hose connections more easily. And it saves weight, the trailer will be lots faster….
