you might be able to get some of the hard nylon stuff from a dealer, otherwise just replace it with high pressure fuel injection line of the approprate size. Regular low pressure line holds about 20-50PSI (depending on size and manufacturer) the high pressure stuff is specially reenforced to handle up to 100 or more.
I want the hard nylon stuff because it's far superior to rubber. When I ask for high pressure fuel injection tubing all they offer is steel and rubber at the parts stores. They do sell a repair kit that comes with a foot or so of the tubing with a connector to splice onto your old line, but I want to renew the whole line. I can't believe nobody around here sells this stuff.
I asked the dealer but he doesn't know anything about anything if it's not listed.
So I'm going to buy it off the net, there's a few different places I just didn't want to wait for delivery. I figured I could walk into any parts store and find it but no way man.
No it didn't crack, I screwed it up myself and I'm too embarassed to talk about it right now. So yeah, I'm going to go to the wrecker and cut a piece of a wrecked truck. I would still like to know who makes the nylon tubing and all it's ratings.
