I need to replace the fuel pipes on my 3.9 V8 as they are well rotten.
My question is what material to go for? I can see several choices; cupro-nickel, rigid plastic, or something else?
I'm not going to use copper due to pressure issues, but any other ideas or suggestions?

I've just done mine - 8mm OD copper end to end. This works remarkably well with 8mm bore fuel flexible too. Use compression fittings if you are feeling uncertain about push-ins.
Don't muck about with plastics for this - while there are many that are technically fit for purpose, there's bound to be an MOT tester or half-wit mechanic who thinks they are not and then you're in difficulties.
Cupro-nickels are just hard to work with for no advantage.
bearing in mind nearly all fuel fittings are push fit plastic i dont think youll find many picking fault
just about to give this a go on my 93 3.9. get a strong whiff of fuel under the drivers side rear arch, cant see a lot wrong but the damn thing is thirsty enough without leaking it as well.
Guessing that easiest way to do this is to get the tank out first?

Interesting - mine did!
update from me, not the feed nor return. Cheers Cooltide i am also thinking filler pipe. i can only smell fuel on the drivers side under the wheel arch, if it had been the feed / return pipes i would have been able to smell it on both sides :/
so how do i get to the filler pipe? i am expecting the wing needs to come off, any tips or nasties that I need to look out for?
Cheers
They are easy access iirc. You may be able to hacksaw rotten bit off neck and get a longer tank to neck hose.
If you need to remove neck just lever rubber washer off at top end.
