Got a propane line coming off the back of my house - directly on the other side of the gas fireplace inside the house. Pictured here:

I'm trying to hook a banjo cooker to it so I don't have to re-fill any more 20 lb propane tanks. Went to Home Depot and purchased a natural gas line kit with quick connect in the grill section - they didn't have any propane line kits.

Hooked it up and it worked. But the flames were pretty weak compared to it being hooked up to a 20 lb propane tank.

Could it be that the size of the hole coming out of the gas line is the cause of the weak flames? Pictured here:

Natural Gas is on the left. Propane is on the right.
