Wow I had no idea it would lose that much power.

I think I have 1/4 quick connect fittings onto a 100' 3/8 250lb hose.

If you don't have enough "juice" at the gun it is likely a CFM issue versus a PSI issue. Most 1/2" impact guns need ~4 CFM @90psi to work correctly and while small fitting and long hoses will cause pressure drops they will have a bigger impact on CFM (volume) and given the small tank size your compressor is likely your compressor can't manage 1 CFM at 90 PSI. With a large hose and fittings you might be able to break one lug nut loose but look at the hoses and fitting on the gauges, they are likely very small. None of this make a difference if you are spinning on the wheel lock!

When people have the "normal" small oilless compressors and want a impact gun I always suggest getting a corded or battery version instead of pneumatic unless they are willing to pop for a bigger compressor.

Bottom line CFM is almost always the limiting factor when matching a compressor to a tool.
