The R4 Compressor on my daughters 300D is leaking at the two pipe connection manifold on the compressor. It is still a straight O-ring type. There is one of the connections in this manifold that has an alignment tube as part of the manifold. The other side does not have anything in the way of a tube or sleeve to align it. Is this missing? Was there something there, maybe on the compressor side orginally?

When I put the manifold in place, the connection closest to the engine has no means of alignment and slides upward enough that I cannot get it to seal.

Any suggestions appreciated.

Have a great day,
