Bryan,

Take a look at the marshal literature page. At the bottom you will see
extend a stay options inside cover. It should show you how the two
hoses hook up. You going to use the small 3/8 fitting on the extend a
stay and the other end is going to thread right into the propane tank.
If you want to use a 1 pound bottle your going to need another small
adapter which you can buy or make. Basically the two hoses you got
allow you to hook up to the extend a stay and other other sides are
universal adapters to fit other adapters. You may need to buy G-475p
or G-487p

If you still have problems email me and I'll take a picture of mine
but I think this drawing will show you what you need.

OK, so I got this deluxe kit (seen here

Depot
last year at a great price. I'm finally out there struggling to get it
installed since my knowledge of propane connectors is non-existent.
One more
adapter and I think I'll have it in after work tonight. My question is
what
hose do I connect to the external tank? If you look at the photo in
the link
above there are 2 hoses, one short and thin and one long and fatter. An
external tank has a large round connector and I don't see that
connector on
either of these 2 hoses. Which one do I need to connect to the
external tank
AND since I will be using the small green bottles do I need 2 more
adapters?

Thanks,
Bryan
