Default Damaged EGR Vacuum Line

My 1987 l98 EGR Valve Vacuum Harness (10046113) ended up with a damaged line during my rebuild and I'm having trouble finding a good replacement. Anyone have one lying around or suggestions?

I'm hesitant to do an EGR delete for two reasons:

1. It's all back together with EGR compliant Long tube headers, I just need to replace this.
2. From what I've read there's not really any benefit to an EGR delete

Edited: include model year

All may not be lost with your on car hard line, if it snapped where it meets rubber and it hasn't done a few times prier you can remove the snapped piece for the rubber and slide in your Hard tube remnant.
If that's possible you can go two ways, either take a piece of Remnant and put it the rubber and bridge the difference with Vacuum line. or get a Double male splice and do the same.

When the 1/8" plastic vacuum lines broke on my '87 I bought 1/8" brass tubing, bent it to match. I drilled out the plastic in the rubber fittings (twist the drill bit by hand) and put the brass in its place. When the 1/4" plastic tubing broke, I used copper tubing. As far as I can tell, the replacement tubing offered on eBay is taken off a wreck. Something about paying $79 for 37-year-old plastic bothers me.


Brass & copper vacuum lines.
