I bought a compressor 80gal 5hp and bought some air tools but I was not satisfied with it, mainly the impact would not bust my lug nuts on my 3/4 ton truck. I purchased a more expensive IR impact with more ft/lbs but it was the same. My little yellow spiral air line that was on the end of my airline got a leak so I took it off until I can get another one and bam, my air tools work so much better hooked up directly to the 5/8 air line. the little yellow spiral line has a very small dia. hole and it was choking my air. These are very popular and I see them everywhere. It bust the lugnuts now with no problem. just a heads up for yual if you use them.
