Forgot to mention the spec of the elbow, B-F6500-06-06 BRASS 3/8" MALE FLARE x 3/8" FEMALE FLARE. 90 DEGREE FITTING, got it from rnlhydraulics on ebay.

Done, it worked. I assembled the whole proses in the attached pdf. I need a new condenser, but that is on the outside of the car, not inside the dash. Brgds Erling Søvik, Norway. Flushing and parts mockup_ Final installation and testing.pdf

Update. Flushed Evaporator with Alkylate gasoline (-for lawn movers etc.), this fluid i mineral and evaporates easily. I don't smoke. Hose inlet connected to R12 inlet on evaporator, hose out in front of Fire Wall (suction). Test fitted all hard ware, did not have to cut the inlet pipe, just loosened the clamp where pipes enter evaporator box and adjusted the pipe by hand. Pictures in the attached pdf.

Hi, The manifold for the new valve is mostly finished, I have not removed the "inboard end" just in case it will need more machining. I will also have to make a steel plate similar to the "flange" on the original valve. This loose plate will enable the manifold to be rotated, to orientate the inlet of the new valve in the desired direction. I decided to make a hose connection so that I can use the manifold also for the flushing of the evap. The first flushing adapter, as shown in the picture in the post above, was made from 40mm Al, which is to small (you can see the O-ring). The new manifold is made from 50mm Al. It is winter now so this project will be on hold until....later. I have ordered an elbow just to line up the inlet to the new valve, not sure if it will fit. The alternative will be to just make a hose from the connection in front of the Fire Wall to the new valve.

Dave, I stumbled over your idea to "gut the original valve" and use it as a manifold. I will follow up with more pictures when it is finished. Best Regards from Norway.

Hi I just filled 6 Oz of Suniso 4GS and 0.9kg r-12. Compressor puls vacuum, so expansion valve is stuck closed. Will pump the r-12 back into a propane tank and try to clean the valve and the evaporator. If the valve is shot I will follow Dave wm' idea to use the valve as a manifold, or not quite, as i will make the manifold in the lathe, with internal treads for a generic valve. If the liquid copper pipe is too hard to make fit for the new valve I will consider to use a #6 hose with a 90 degree to the valve.
