Running fuel lines, any tips
Turbo Mini Forums

Just ripped out all the old steel fuel lines and am about to replace with 8mm copper microbore.

Any tips on how to navigate the pipe up and around the rear subframe in to the tank? It seems really tight to be able to bend it up and around the way the old fuel ran.

It's possible so long as you use a good quality microbore tube bender and run it with the subframe off. I've done mine 8mm (flow) and 10mm (return) copper microbore but without the proper bender it just kinks on the tight curves. Also make sure you use brand new microbore - copper work hardens very easily so never re-use old stuff.

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

If you know how to solder copper pipe ie for house fittings you can do the same for your fuel lines. Save bending, just cut to length and use ninety degree fittings job done. send GinoR32 a PM as I saw him do this to his car.

I cut mine at the end of the floor and ran rubber hoses from there.



You won't get the copper behind the subframe with it still on, and it'd be a bugger to get the subframe off if you route it over it, hence my solution.

thanks,for the advice think I will cut it at the subframe and join it with flexible pipes as you say. Just dont fancy dropping the subframe. Plus I have 10m of the stuff so can have plenty of practice!
