Way to connect Champion LP hose to mounted propane tank?

If a search doesn't find what you want go to a propane shop and have a hose made. Or replace with the parts I posted above.

I have the extend-a-stay installed with the 2 ports for hoses prior to the MH regulator. The regulator that came with the generator attaches directly to the 20lb tank and has a short hose with a quick connect into the generator. Is there an adapter hose that I can attached directly to the MH tank and screw into the regulator input?

Champion equips their generators for several different kinds of propane hoses.

One version has just a conventional high-pressure regulator on the hose (which feeds a second low-pressure "zero demand" regulator located inside the generator itself).

With this type, the original hose can be discarded, with the generator instead connected to the RV propane system at any point after the RV's regulator.

Basically, the RV's propane regulator takes the place of the regulator mounted on the original hose supplied by Champion.

Another version has both the high- and low-pressure regulators installed on the hose (in which case there is no other regulator inside the generator itself).

This type can NOT be directly connected to an RV propane system, since it would lack any means of automatically shutting of the propane flow if the engine stopped running.

I tapped into the low pressure side. The key is separating the Champion regulator from the 'flow control' part. When done the flow part has quick connect male fittings on 2 short hoses. Don't get confused which way it mounts!

It's called Extend-A-Stay, you can get one at Camping World, or most dealers.

Search for the needed adapters, these from Amazon. I tapped into the high pressure side but low pressure adapters are available.
