Addition: Ran tests with #5 blue Floodjet tips, high gear wide spray Output looks to be about 0.28 gal/K. So one tank would cover around 43K sq ft with the blue tip vs almost 60K sq ft with the gray tip. Machine running at 3400 RPM wide open. I guess the thing I am curious about is why I am only getting like a 7 ft pattern? Literature claims 11 ft, no way jose.
