Leaking transmission line

Best to cut out and replace with steel line and compression fittings. Hose will fail in time

I really Doubt it!!!

We tried that on a brake line on 1960s CJ 3B Jeep

It did not hold long!

I suggest that you Cut thru OR cut out your hole

If you have enough room Slide the correct Flare Nuts down each of the lines then DOUBLE FLARE the ends of the lines

Then insert a Double flare coupling and tighten it all up!

You must weigh out cost/ time trouble of replacing the line VS: Double Flare coupling and tool

THIS IS NOT A PLUMBING FLARE TOOL (I KNOW, IMMA PLUMBER)!!!!THIS TOOL WORKS SIMILAR EXCEPT IT ROLLS THE FLARE INWARD TO MAKE A TOUGHER SEALING SURFACE.......You might buy a short brake line and practice a few times before you....GO FOR IT!!! Cut the lines with a tubing cutter if possible...or a sawblade--dremel tool---keep it "Square" on the ends!

Rubber (fuel injection) line is used quite often from the factory on cooler lines. It is more than strong enough if installed properly. The biggest issue is how it is done. You can't simply cut off a steel line and slide it over. The line needs some kind of flare in it to prevent the line from sliding off in time. It also need to be positions so there is no sharp end of the metal line pushing sideways on the hose. Make sure it inserts straight in the rubber line and it's a good idea to double clamp at each connection.
