Retubing fuel/oil lines

[gnavs]

I've been toying with the idea of replacing my dirty old oil feed line to the turbo of my AAZ with stainless steel instrumentation grade 3/8" tubing.  I've worked with this stuff before and am quite capable of bending this stuff as its part of my job.  I've tubed pneumatic and hydrolic systems on large oilfield compressors with this stuff so i'm not worried about the tubing itself, its mainly the connections (thread pitch etc).  For the oil feed i'd most likely use a 3/8" OD x .035" wall thickness.  As for the fuel lines from the IP to the head, well thats still up in the air.  If i can find proper connectors that will match up to the existing stuff it should be easy.  Its mainly a trial and error thing as far as connectors go and I can get the supplies from work.  
Mainly looking for any info on the pressure of the fuel going to the head to see if it will be within the specs of the tubing (i'm pretty sure it will be)Any feedback from you guys would be appreciated.

i have thought about the vibration issue, but not really the expansion.  I really need to do more research into the capabilities of the tubing before proceeding, but at this point i'm pretty sure it can handle it.  This stuff is run inside, outside, along giant diesel engine blocks, etc.
So the 2500 psi, i take it is the fuel lines pressure?
