It was just a thought. If it were me, I think I would break out the BFH and prepare to replace it all. As you have said several times, 51 year old car. Those lines may need to be retired anyway.
Well Mark if this car was not in such great shape I would. Car is untouched underneath, no undercoat and no rust anywhere. The line itself looks fine as does the connection. It is a one piece "home run" line that runs from distribution block under MC to back end along frame rail. Car was restored by PO in terms of paint/body/interior/engine on a car that appears to have led a well pampered, garaged, western US car
There are likely repop lines available but this is one looooong line. Longest on car and I really don't want to splice it. Worst case I would cut the fitting, re-flare that end with a new flare nut. The flex line that attaches to it gives me some wiggle room but I likely would need to re-mount the bracket both hard/soft line attach to if I cut the end to re-flare it. Of course getting a flare tool in the area may prove to be a bigger issue.
the 3 factors on this is the location is hard access,the fitting is frozen and so far flare wrench and vice grips, heat and PB are not doing it. Primarily because no tool grips enough on the fitting and with the vice grips I just can't get the angle needed to apply them properly
I bent over and ordered the line tools from ebay….will see if they do the trick. The video demo shows how they clamp tighter the more force is applied and it is a 6 sided end for the fitting unlike a flare wrench
The OER 6020 6 sided vice grips are also available,,,,similar $ but I can't get vice grips in there at a perpendicular angle to correctly go "around" the fitting
this is not the 1st "specialty" tool I have purchased....ideally it works
