We pulled out our propane regulator and tubing with the thoughts to replace them, we've had the cabin over 10 yrs and the regulator is probably closer to 20yrs old. We wanted to go to stainless sleeved hose, since the critters chew on the rubber hose. We were a little stunned by how small the inner diameter of the hose was and think that it might not have ever been sized appropriately for our set-up. We operate the cabin with alternating between a 20-lb and a 30-lb propane tank. Does anyone have experience sizing propane regulators and hosing here? We have an old Caloric gas range (4-burner and smallish oven/broiler), a propane fridge, and 2 gas lights running off the current setup. I'm not sure if I can get the BTUs for each appliance since we are back home till next year, but I can try to estimate. We pipe the outside line to a 1/2" black iron manifold with several take-offs (yellow flex lines to the fridge and stove and 1/4" copper line to the lights, all have their own new shutoffs)

So all the appliances run off 11WC? That's about 1/2psi. There is no real propane hog in your setup and some are even intermittent use. Where you having trouble with the system?

I believe most fridges are 1lb of propane per day. If you have the typical gas lamps are 11btu. For a stove top I would say between 15-22btu per burner. No clue on the oven.

3/8 copper is pretty easy stuff to work with as far as bends and flaring. Check all connections with soapy water.

We are just looking to replace the old regulator that is outside connected to the small "grill-sized" tank (we swap between our regular 30, and the 20-lb spare) because the seals might be going bad due to age, and the rubber hose from the regulator to the black iron manifold since critters keep gnawing at the rubber and it's seal is cracked. All the stuff on the inside is new, 1/2" yellow coated appliance hoses to the fridge and stove. The 2 lights are the only thing in copper. We just aren't sure if the regulator was correct, it is a Marshall model 260, 2-stage lp reg, listed 605H, outdoor use. The hose is a 1/4" POL line, but we weren't sure if that was the correct connection from the tank to the 1/2" iron manifold in the cabin, or if there should be a different size or hose we should use. In a typical week we are going through about 20-30 lbs of LP.

Post pictures of the current regulator and lines please.

I have used the stainless braided propane hoses. The stainless is just crimped in the ferrel on the end. In my case this pulled out and I was left with jagged wires hanging out. My other setup had a regulator mounted on black pipe with a soft copper whip to go to the tank. This setup is way more robust.

I believe your looking for a pigtail.

The hose from outside connects to a black iron pipe that extends to the outside of the cabin from the center tee of this manifold, just to the left of the vertical take-off. The vertical is to the lights, the left yellow hose is to the fridge and the right is to the range that you can see the edge of in the pic.

Looks to be an old camper regulator. It should say 11 or 12W.C on it some where. That's a pretty standard pressure. Since rodents chew your rubber I would replace the rubber piece with a copper pigtail. Those are all pretty standard propane parts and I'm sure if you know the pipe size you could find them in many places online.

I'd you wanted to use a rubber hose again I would get one with a standard ACME fitting on the end. No tools needed to change your tank.

If you do go back with rubber, you can cover the hose with a SS braided hose sheath:
