I need to connect a 10mm steel tube to a hose assembly with a -6AN end. now 10mm is real close to 3/8" so I am tempted to just slide on a -6AN tube nut, try to flare to 37 degrees using a 3/8" flare tool, throw on a union, et voila. However, the engineer in me says that is wrong, wrong, wrong and that I should use an ISO flare and an adapter to -6AN. The problem is that I can't seem to find either tube nuts for the ISO flare or the adapter to -6AN. Any ideas?
Application is a fuel line for a Porsche 944. The 10mm tube is one solid piece all the way back to the fuel tank from the engine. At the engine end a rubber hose is factory crimped onto the tube. The hose is known to split, and it is conveniently located above the headers. This is a somewhat high pressure app, 40 PSI or so, and fed by an electric pump at the rear of the car. Hence my desire to replace it with Aeroquip (cutting the tube back to inside the wheelwell so that the obvious failure point is not RIGHT above the headers...) before it becomes a carbecue. If I can make it work not only will it look sexy but it will be a hell of a lot cheaper than dropping the rear suspension to replace the stupid steel tube, which is in fine shape, just the hose is gone (actually replaced at the moment with some high pressure hose simply clamped on with t-bolt clamps)
thanks!
