You will likely find that the Yorkie actually belongs on a Kenworth, not one of our rather puny 220D's. You will often need to shut it off when taking off up hill, and it is a royal pain when attempting to do a water pump replacement. That is the job that caused me to ditch the Yorkie on our 220D. To use some other compressor would take a custom bracket, but that welded up monstrosity on there now is a custom deal anyway. Good luck!!
