Paul, I didn't get the hose from Burbach. Why is it a screw up? That is the Rad End of it. This #230 hose looks just like the #186 hose pictures you posted. I looked through my collection of buildsheets (30 years worth) and could not find one buildsheet with a #30 for the upper hose. I'm thinking the #186 superceded to the #230. What do you think?
