I need to replace the ps pump on this van and I've got everything loose except for the pressure line hose. I've got the correct 16mm flare nut wrench/line wrench for the hose fitting but I can't get the thing to break loose. Any suggestions? This is the only thing I've got left to disconnect before I can replace the pump (I've still got to remove the pulley of course).

Do you have room to put a small piece of pipe over wrench or interlock another wrench on it for extra leverage?

Well I finally got it loose with a big crescent wrench so now it's out of the van and on the bench, but now I can get neither the pulley off nor the hose fitting off that the hose from the reservoir hooks into. Why can't anything about this job be easy?!

Update - I finally got the thing swapped out and that seems to have fixed the problem, which was loud groaning and strong shuddering at low turning speeds. I've seen other people's posts about replacing the reservoir to fix this same problem because of the screen/filter inside the reservoir getting clogged but no such luck in my case, the filter was clean as a whistle as far as I could tell.
