the 1/4" ss was all i could find that had a 3.5mm id or there about its some kind of thick wall hydrological line
i think it could as you say be shaved down just enough to get in the fittings ie chucked up in the drill press with some fine emery paper should work i think

the 6.35mm is what i measured so its a bit over size for a 6mm fitting given the olives are actually 6mm and not over or under? but that shouldnt matter if im slimming the tubing down to fit..

yep ive got a few 1/8 ntp taps so will need to use the method you have said try it cut a touch more try it so on

shortest, straightest, easiest path for my feed lines it is then this will help the condensation too

kind of a pointless addition to the thread but hay..
my ss fittings are on the way and ive taped the threads in really shallow leaving plenty to work with for the new fittings i did this as i wanted to get the brass fittings in to guide me so as i could get the pipes bent up into the rough shape leaveing plenty to hand bend and tweak later witch worked really well

i think the ss bent a lot better more uniform than the copper/what ever else the coating/pleating for the steel fuels did probably due the the ss being thick wall and the fuel lines being kinder thin?

anyways waiting on the ss fittings two are 90 and two are straight this allows the best layout of feed pipes i think..?

is it worth making the 3rd 18x1.25 threaded bung for O2 after the turbo to check the readings from? this whould require me to move O2 sensors around hole to hole as i dont want to buy a third one..
its no problem to make the bung as ive got the tube and tap so if it could be a benifort to tuning ill do it but it i need 3 O2 sensors to get the advantage ill not worry about it i think?

also regarding that nice thermal sleaveing stuff would it still be ok to use it on the quite short feed lines with out over heating the O2?

id really like to cut down on under bonnet temps as much as i can so any heat i can keep inside the exhaust and send down the tail pipe is a grate thing!

Schrödinger's cat - so which one am I ???
