How much of this problem is the return orifice on the MRA vs the reg? AFAIU the factory MRA is also a pinch point for return flow. Sorry for the thread mine but it's an informative thread and I wanted to clear this up. Link to comment Share on other sites More sharing options...

There's a steel collar in the return hose that has to be drilled out or removed. Link to comment Share on other sites More sharing options...
