I agree with the previous posts, 200 ft of 3/8 hose
Never noticed he is using 200 Ft of hose

Max should be about 50 ft and it would need to be 1/2" for that distance.
In our business we had an air installation in the workshop, that consisted of an air ring main in 1" bore galv pipe which served 8 FRL take off's. The shop was 4500 sq ft and 40 mtrs long, 2 of the FRL's were at the end of the shop on either side and the compressor was in the middle of one side. All the tool air lines were 1/2" x 30 ft max, blow lines were 3/8" x 50 ft max. Even then the tools used on the most remote FRL's had less poke than those nearer to the compressor.
The compressor was an HPC screw, 40 CFM.




.......have you tried with both hoses attached as well ?
