I'm in the process of adding engine driven A/C on my MC8. I have mounted a new condenser in the pass side engine access door, and a new Sanden compressor (Using R134) on the 8V71.
I am using the factory evaperator in the dash, and I have added a second evaperator underneath one of the dinette seats.
I had assumed the we would just use the factory a/c lines that run in the tunnell thru the bays.
My advisor thinks the lines are too large for the compressor. He thinks it would be better to run new rubber lines.
Thats fine with me, But I can't see a way to get them into the tunnel at the engine end.
Anyone done this? Use the factory lines or new rubber ones?

Chuck check with the folks at Welch Industries they are in GA I can't remember exactly where, and I've lost their #. They specialize in after market A/C units for the motorcoach industry and should be able to help ya out! I'd think they could be found online. BK |

Can't you use the existing lines as conduits for you new lines? |

Chuck, just a WAG, but how much too big? Seems to me that you may be able to use these "too big" lines as conduit and just run new, smaller lines inside the existing ones. ???

Not that I have ever dealt with them and can say ya or nay for referals, but Welch Industries is at http://www.welchindustries.com/index.html I am not so sure about using more very expensive "rubber lines" than you absolutely need as R-134 A is so small that it is the most easy to leak refrigerant available (which made it the perfect manufactures choice). If you need smaller lines (not sure of the efficiency wisdom here if the cold lines are insulated) then perhaps run smaller metal lines after your condenser and only go to "rubber" lines , in short spans were flexibility is warranted. |

I did on my mc8 just what you are doing, I run the rubber lines through the channels under the bus and cut a access hoe into the channels for entry in the center compartment where the old ac and heater fans are. also run a line all the way to the spare tire compartment. Worked for me. |

As mentioned above R134a will leak through hose designed for R12. I cannot remember off hand what the name of the hose designed for R134a is. If you need help getting the hose email me. My father in law works at a place that can make custom sizes of it at a resonable price. |
