Fuel lines breaking

I'm having issues with my 7.3L IDI turbo setup breaking fuel lines. Do you all run fuel line supports to keep this from happening?

Do you have the line clamps on?

Yeah. Go to Midwest Fuel Injection, on-line (site sponsor) and you can get the ones meant for the 7.3 Navistar engine. I can take a pic of mine so you know where they go and how many you need.

Does anyone have pictures of their fuel lines with the supports? Or is there a diagram online? I have not seen anything through those links. I assume clamp location would be important.
Thanks for your help.

Sorry, got caught up with some reloading. It's dark when I leave for work and dark when I get home. If you can remind me this weekend, I can post pics Sorry again.

Your welcome. I just looked at my photobucket albums and found a couple of pics that show the D/S clamps. Just click on any of my links in my sig, and then look for the "powdercoating" album. I will take better pics this W/E.

What is the most popular fuel line to break? And why does it break?

I had pitting on the flared fitting that connects to the injector causing it to leak
