Hello all again, it has been awhile since my last post but I have been "lurking". Some of you may recall my earlier posts regarding radiator choice as I was weighing re-coring my original radiator vs replacing with aluminum radiator. I elected to have the original radiator re-cored with oe style copper/brass core. The rad shop I used convinced me to go with 5/8" dimpled tube for better efficiency (30%) even though the 5/8"core has three rows rather than four with the 1/2" tube. I had Seattle Radiator due the job after meeting with Lou, the owner. They also refurbish fuel tanks for those who are interested. The radiator currently sits in a box inside the coach while I scrape and brush the accumulated grit and goo off of the frame where I will re string the lines. The existing trans lines are rusted,dinged and have been cut to splice in the auxillary cooler. I wish to replace with new steel lines from the trans out but was having no luck sourcing 5/16" line from local parts jobbers. I was able to find a supplier of steel 5/16" line(Marmon Keystone). Here is the question. The line is available in bulk only(minimum $150 for order) and can be ordered uncoated or coated with zinc. I know I dont want bare but is zinc ok for transmission line use? Also since I have to spend $150 or more I thought I would buy some of the same tube in 3/8" for fuel line so same question there, zinc ok for that? Since I am asking questions, the wall thickness of the 5/16"tube in question is 035. Is that about the same wall thickness as the original? I plan on bending and cutting to length followed by flaring the end of the tube with a hand tube flaring tool.
Thanks in advance to your replies.
