AC line

the AC line, right where it goes into the liquid tank ( as MB calls it in the EPC) has a crack.

Replacing the whole line - it disapears behind the cabin air filter/heater box seems like quite a task. Anyone done that already?

I am wondering whether there a fittings to connect a hard (aluminum) ac line - the I could just replace part of it.

RE: AC line

If you can move the receiver/dryer back a cm, then you could push the nut back along the pipe, cut the existing flange off, and form a new flange on the end.  

I have wondered about the wisdom of having the R/D bolted to that spot.  That part of the body vibrates a lot, especially on washboard.  That could certainly explain a cracked pipe.

Hi Alan,

not working, unfortunately - its a crack along the pipe. From the flange to halfway to the fitting with the sensor :-)

$50. But, if I consider that I now don't need to take half the car apart - then it's dirt cheap
