I appreciate what your saying and understand that filling another tank 3 times the size would tax the small compressor and I did mention that it was a band aid for a broken leg scenario. I was trying to give the OP some direction in which he could use is compressor and prime small areas...I'm thankful that he's looking at other solutions.
