I'm think I am going with brake and fuel lines from Inline Tube for my restore project.
Their prices are competitive and - after talking to a couple of my friends who have used their tubes - I feel comfortable that the product is good. And trust me, these guys that I asked are
real picky about their trucks - they're like fanatical.
Word is that the tubing sections that Inline supplies are bent very close to factory configuration and - for the most part - the materials they use are of good quality. But even as close as the shaped tubes are to factory, expect to make some field adjustments.
Also, if you pay the "slight upcharge" for stainless steel fittings - make sure you get real SS. It may just be rumors but I've heard they try to skate by with low grade stainless.
I know I will be preaching to the choir when I say this, but it bears repeating:
When it comes to renewing brake/fuel lines (or any components that are not normally accessible), it isn't about the money. It's about the quality. Changing brake lines is a pain in the ass. Nobody wants to do the same job over again in 5 years. I would gladly pay twice the going rate if I knew for sure that the brake lines I installed were going to last for as long as the truck could be kept running.
