The Range Rover EAS (Electronic Air Suspension) systems operate @ 140 psi which is the primary reason I snagged the tank. Unfortunately the electric rover air compressor on that truck was toast. I guess I should have been more clear- I was looking for a cheap electric compressor recomendation. Using a York or any other engine driven compressor isn't an option- although I did see a home-made starter motor driven, York compressor that would probaby have fit in the seat box under the passenger on ebay a while back.
