Fuel Line Replacement

[Big Musky]

Hi Guys

What is the best material to use to replace fuel lines? I have decided not to cut out the bad section and replace it. What is the best material to use, plastic, copper for example and can these be used throughout the fuel system. Tha car is a 2005 Ford Mondeo Mark Three 1.8 Petrol thanks.

For hard lines? OEMs used to use steel I believe, but these days are plastic of some kind. If you're making your own up, rather than buying new ones, copper pipe is the usual stuff. Most (or at least, a great many) kitcars are done with that.

ETA - you really want to by a flaring tool to flare the ends, failing that you can get the same effect by soldering an olive on the end. But you should have something, given the pressures in fuel lines these days.

Cunifer is preferred over copper, but is harder to work. If you use copper, make sure it is very well supported because it is vulnerable to fatigue.

I haven't installed any nylon/ptfe fuel lines but they seem to be the fashion these days and look easy to use.

Thanks to you both for your advice got a better idea now what to use.

Yep, I did all my brakes with cuinfer for this reason, it was a pig to get the flares right though so there are pros and cons. I imagine that large bore conifer pipe might be rather difficult to bend to shape without a fairly meaty bending tool.

On the TVR it's basically rubber fuel hose everywhere and just strapped to the chassis. (Might not be so easy to mount that on a monocoque tub but the hose itself is dead easy to fit.)

Why not just get another hard line off a breaker?

I had a look at used lines off a breaker but they were quite rusty too. Mondeo Mark three is getting older now last one was 2007 I think.
