Trying to resolve a PS steering leak. Leak is due to the different ODs of the connections on the cooling line and the low pressure connections on the reservoir and steering box. There's about a 4mm difference in ODs and can't clamp the smaller ends enough to stop the fluid leak. Thinking I need something with a compression fitting on one end and barb on the other. Compression for the cooling line and barb for the hose. Or something. Anythign like that exist? Any other ideas?
