What shop did the quote? I live in south scottsdale and i may need to replace mine.
Rmacc hose in Glendale. Roughly Grand & 67th. I've heard a lot of good reviews of people going there and getting lines installed cheaper than you can buy them for.
If you go, check out the Chrome Guy and Mark's bolts, both located less than a mile away. Mark's is where I try and buy all my hardware. $6 a pound for Grade 8 and tons of SS, Metric, etc. all in stock. The Chrome Guy stocks a lot of parts for Chevy trucks, like a mini LMC, comparable prices, good service.
Also, for full custom/ hot rod, there is AZ High Test. They do show quality lines.
