Helping a guy out and have hit a wall. The braided hose has failed on injector 1, injector 2 looks to be just starting to do the same. My issue is those crimps that hold the bottom of the fuel line to the injector. Pulled out the blue books and they look to be OEM that way. Am I right to think that if I cut away the crimp and peel back the old line I could push on a new piece of line and then drop a hose clam on it? Have put the @sfdon signal out but think he's off spelunking. :)

I believe that the metal stalk upon which the hose is crimped contains a few barbs to help retain hose. Service kit makes injector look like this:

As an aside- the fabric covered hose looks great while it conceals the cracking in the rubber below.

I know that now...
My operating assumption is that if I carefully cut away that bottom crimp and expose the barbs on the top of the injectors I can then push on some new hose.
Probably pay to do the injector seals while I'm in there as they are the next likely failure point in the fuel system.
 
I’m cutting one up this week Wes- let me know you need.
 
So by way of an update, as with most things E9 related, what looked like a simple job took half a day and I'm only half done.
It appears all of the braided fuel line is OEM and 50+ years old and super brittle. How this thing didn't burst into flames at the first pot hole I'll never know.

Just to make it more fun there's the RHD aspect, which means the car had to be jacked and the LH wheel taken off so you can get under the car to access the hose clamp where the braided line meets the metal fuel line as it's all down under the brake servos.

In case anybody else is reading this with the same issue of those OEM crimps on the injector hose I can confirm that if you remove the injectors from the car you can VERY CAREFULLY - (LIKE TRYING TO ARM AN ATOMIC BOMB) - grind off a section to reveal the rubber inner section. If you are then REALLY REALLY REALLY GENTLE - LIKE DEFUSING AN ATOM BOMB GENTLE - you can twist off the old line without damaging the top of the injector. The injector 'inlet' - the bit the crimp sits over does have a barb on it so you can simply push on a new hose and hose clamp.

Tomorrow after a couple more Valium I'll put it all back together and turn the thing on. Stay tuned.
 
Ok, so. Another two hours today bashing knuckles but I'm happy to say that al of the original perishable fuel lines are out of the car and now in the bin. Getting the fuel rail back in the car was pretty fiddly but worth the effort. Put the whole lot back together and fired her up. 10 min idling and no visible fuel leaks or even a strong smell of fuel. Pretty happy with the result. Was a total nostalgia fest in my shed, working form the blue books and using the OEM tool kit for most of the work - just because I could. Can't say I noticed a difference between using a red or green handled screw driver!
Reading that last sentence back, I'm such a fricking nerd. :)
