Mine were heat soaked and cracking, exactly 50mm length on each of 8 injectors. I didn't have a proper hose cutter, so I stuck a metal pen into the hose and used a sharp tubing cutter. Gave square ends.

4 other hoses in the front of the car need the same treatment. (will post that work later).

Here's some random photos of the job. Other, better treatises on the subject are in the archives. I'm glad I didn't postpone refresh of these hoses. Very important, as many before me have said. So, if nothing else, use this post as a reminder to check your fuel lines, too.

928'sRUS has kits (and some special expertise in high-grade hose specs). I tried sourcing locally, but the hose is very expensive around here, and everybody wants to substitute something else, and the clamps are hard for me to source, too. (Just buy the kit). Other suppliers also may have similar kits.

I was going to t suggest that while you had the injectors out, send them for cleaning. I sent mine out and $20/ea, its relatively cheap piece of mind.
Also, keep an eye on the small o-ring while you're putting the injectors back in. Between the time I slid them on and installing the injectors, the small o-ring on #4 cylinder disappeared. Huge performance detractor.

Nice work Chris.

Similar to my solution...

The only difference is I didn't use a hose clamp on the injector end.
