routing brake and fuel pipes

[Blatman]

And solid hose is lighter than braided when all's said and done.

In use, I agree that there will be no problems with expansion (or anything else) using braided hose throughout the car, but for the seriously weight conscious, there is a small consideration to using Kunifer/steel hard lines.......

Thats it......cat out, pigeons everywhere.........

but there are no specific down-sides either.  IMExperience....

it does cost a tiny bit more than normal pipe though  

To be honest, by the time I got to that stage I had stopped counting....      But I *hate* making solid brake pipes with a passion - all that faffing about with flaring tools and trying to get a decent seal.  Pah !  Give me aeroquip hoses  any day !!
