I mocked-up the hoses to show how I'm planning to run them. I agree with you that I should use steel fittings. The 180 and 45 degree fittings seem to work pretty close to the way I'd like them, except the 180 degree fitting is a little taller than I planned and there isn't a lot of clearance for movement of the compressor during belt replacement. If I had a 180 degree fitting that laid closer to the compressor, it would give more clearance.




This is where I'd like to mount the inline ports. Actually, I have been considering installing an accumulator with an R-12 fitting in place of the low pressure port in order to protect the compressor from liquid refrigerant reaching it and adding extra cooling capacity to the system. However, finding one with an R-12 fitting may be difficult (both now and in the future if it needs replacing) and it may be overkill on an expansion valve system, not to mention cumbersome. Sure, Mercedes didn't use them until the W126? but it could potentially save the compressor. I don't know.
