Thanks Gentleman for the explanation and the good advise. When I went through the www I saw some kits but my concerns covers your advise exactly.
We drive our cars sometimed tough and if you have more of these adapters installed the risc of leaking is much higher. I am not the guy using a hammer for replacing an oilfilter but due to the 180 degree manifold space is limited.
The challenge continues
David, do you may have a photo of your system?
Again thanks for all the feedback
