replacing T350 fuel lines
Discussion
Hi
Having seen the recently reported Tuscan fire and a number of forum posts about cars of my age (2004) having deteriorated fuel lines I am considering replacing them. Has anyone done this and how easy is it? I'm thinking of going the PTFE lined route. Has anyone experience with this?
thanks

Not easy. Not impossible but you need to get the car up in air and have a mate who has a sense of humour. Wooden wedges to ease the body up off the chassis over the tunnel, kind of brutal but the only way I could make it work. You will need to lubricate the new lines as they pass under the heat shield blanket as this can ruck up and block the path. I had mine made to length and covered the end I was pulling through to prevent debris getting caught in it. I used the old line as a pull through.
Once you start it’s got to happen so get a few packs of bacon in for the banjos, you’ll need a brew on the way as well

Given the possible consequences of a leaking fuel line I would have hoped they replaced both feed and return, unless they are made of different material, which seems unlikely. My car is over with Sussex TVR next week, I'll get John to have a good look at the fuel lines.
I know the lines are meant to be a service item. Does anyone know at what interval?

Different material. Pressure is nylon pipe, think it’s nylon, and with crimped banjo unions. The return is rubber.
The nylon had kinked by the fuel rail and there was not enough slack to shorten and fit the banjo again, anyway decided time to change the pair, so a phone call to my mate Smiffy and a trip to Mr Patel’s mini mart for the bacon fuel for Smiffy and the job was on. The nylon did feel as though it was “set” and rigid so maybe the fuel or additives are having an effect?
Should have done them both in PTFE really, anyway engine and box out again soon for another series of upgrades and will do it then..... sssshhhh don’t tell ‘er indoors.

It's the bio-ethanol that is in Premium Unleaded (95 RON). If you only use 97 RON you won't be affected, but that may all change in the future. Nylon looks to be much more resistant to ethanol than rubber, but there is an interesting article in the link where the makers of SU carburettors are saying avoid Nylon. For now I'll start using 97 RON and replace both lines with PTFE in the near future.

Pay the extra and uses Braided PTFE lined fuel lines. No worries and no vapor leaks.
