I am aware that it needs to be routed so it doesn't rub against any hard surfaces but does anyone have first hand experience using aluminium fuel lines?

John I've never come across aluminium lines in any British / Euro car. Not to say it doesn't exist but not sure what the properties of aluminium are in this application. I've just installed kunifer fuel lines from tank to engine compartment without too much difficulty.

I saw a Healey being professionally rebuilt a while ago and they were using aluminium fuel lines - I think the guy called them Hycot or something. Anyway the Goodridge fittings looked very tasty!

I use internal Braided PTFE lines via JIC bulkhead fittings. Copper and aluminium both work Harden over time so they should be secured over there length and as now rubber tubing taken from the secured end. Obviously corrosion in alloy could be faster than copper or Kunifer.

Aluminum fuel lines are common in aircraft. The problem with aluminum is our modern fuels with corn alcohol added is very corrosive to aluminum.

We don't have many cornfields down here and although our fuel is 3rd world quality those blends that have ethanol use sugar cane and they very rarely contain more than 10% and are in the lower octane category. For a short time we had E85 but it never caught on and created all sorts of problems when the humidity hit in the warmer months in parts of the country as ethanol is hydroscopic.

What I don't know yet is when Australia is going to Euro 6 emmisions and as our current fuel blends won't accept that standard, what we get is anyones guess.

My thoughts of using aluminium is its ease of use and my current lines have too many rubber hoses through the length that I'm comfortable with especially as I'll be putting 60psi through it, also I'll be rerouting it to the back of the engine bay. When I've used the steel tube, ours has a copper lining which maybe the same as Kunifer but down here it's called bundy tube, I have wasted more than I've used.

I have looked up to try and find out what I was talking about in my earlier post - the Healey rebuild with aluminium fuel line.

It was Hycot. It turns out this is a trade name for a polyamide coated aluminium tube made by Norsk Hydro. It seems to be widely used and apparently Bentley are using it in their ‘flex fuel’ 620bhp monster that will run on E85 or petrol. Goodridge sell it with the fittings - no flaring required.

Clarify lines and hoses. Lines run under the car and are subject to everything the tires kick up to nick and damage them. Aluminum wouldn't be up to the task and probably is illegal in the US. Here it has always been a steel base often with lead in the alloy. Cupric nickle is the fashion in Europe and now accepted in the US. Fuel hoses are another matter.

I'd make sure it has compliance in Aus. It may require stringent install methods as alum breaks/cracks quick under vibration etc.
Diesels fuel lines work around 60psi from the tank to the injector pump and they are all steel.
