Imagine assembling your engine like this, in your garage

I agree,especially with a 3/4 impact, i call mine the howitzer. I dont need it often, but it chokes on my 3/8 air line. Have to wait for pressure to build up.

When I moved to my new shop I went with high flow fittings and the difference in hole for the air to flow through is shocking.
