been looking for a on-board air conpressor. something with 100% duty cycle@ 100 psi or so.so many makers i dont know a good one from a bad.I have a three gal. air tank already mounted and hard lined to the left front wheel well. I figured i'd have enough room there. I'm not opposed to an engine mount model but,my harrison air compressor still works, and besides my 75' k-5 has dual batteries. So, can you guys give me some helpful direction on what equipment to choose? This is only my second thread i'm new at this but i've got alot of great ideas from this forum in the past.
