Not sure how doable this will be. My champion 3400, has a high flow regular. Not sure, what the required flow rate is and if the tt has enough flow and if it can be regulated.
If there is enough flow. It looks like the hose, will have a same male coupler on each end. This could be a safety issue, if it is disconnected at the generator. That issue already exists supplied regulator and hose.
Here is an old link that might be helpful
