Does E10 fuel damage fuel lines?
Ethanol is hygroscopic, which means that it absorbs water from the atmosphere. And that water, in turn, finds its way into your car. This can lead to condensation in fuel tanks, fuel lines and carburettors and cause corrosion in brass, copper, lead, tin and zinc components.

A recent post on another thread raised fuel line E10 compatibility issues. Can anyone point towards a suitable make/supplier of suitable hose. Needs to be E10 and fuel injection compatible. What are others using? I think we have until Autumn when the E10 comes into use? So will be a next winter job for me I reckon. Thanks, Ian.

Gates Barricade; note they do versions for high pressure fuel injection systems, and low pressure for use on carbs.

I think it will be a long time before petrol goes completely, absolutely. It's distribution on the other hand is going to steadily change in the coming decades.

Hi Dave. I think I will change to barricade. Any suggestions on the best place to buy it from.
Jimbohuc
Bit of topic but probably relevant. E5 will remain in ‘super’ higher octane unleaded.

Will my zetec black top needed to be remapped to run on E10 supper unleaded. Thanks in advance.
Why E10 petrol?
In theory the use of E10 petrol is an environmental move, intended to reduce the fossil fuel component of vehicle fuels and therefore combat climate change.
What can classic owners do about E10?
Owners of modern classics can use the government’s online checker tool which uses information supplied by car makers as to the suitability of the fuel system. Information is patchy but has improved since the online check was first offered and for many brands the system will go as far back as the early ’90s.
Modifying for E10
If you plan to modify your car to suit E10, it pays to proceed with caution. Sadly, some of the parts available for the job could be sub-standard and potentially cause more problems than they solve. Perhaps the most worrying of these are fuel hoses purporting to be ethanol-safe, but actually not being up to standard.

Fuel hose tips
Alan at Volksbolts offers the following tips for replacing you fuel hose with good quality R9 hose:
Pete Lewis
following lots of ebay crap marked as R9 but useless so thanks for the link
dougbgt6
I've just had a hose disintegrate internally restricting fuel to the carbs. It was 4 years old and marked R9, Ebay Chinese! So I installed the Barricade which has been sitting on the "to do" shelf for a couple of years. Trust only the Club shop! Well, mostly.
andybeau
There is an article in this months Practical Classics with reference to E10 and supermarkets.
poppyman
im a firm believer the original fuel hose was made to a specificationand it lasted years the recent problems all stem from
andybeau
Another thing to say is that surely classic cars like Triumphs should be using super/premium unleaded which is closer to the old 4star instead of the 95 standard unleaded. Premium is staying E5 for sometime apparently.
Pete Lewis
certainly yes,, i wont be putting lawn mower fuel 2* in mine whilst fuels have changed over the decades 95 ron was mowers and side valves when our cars were developed
Iain T
Just bought some 1/4 and 5/16 hose from the club shop and it's marked up R14 which is very high spec.

Older fuel injection systems such as Bosch K-Jet may require elctronics hardware changes to cater for the use of these new fuels. Tail-pipe emissions of CO2 decrease due to the lower Carbon-to-Hydrogen ratio of Ethanols.
Does ethanol help with air quality?
The molecular strucutre of Ethanol allows the fuel to burn more completely and therefore give cleaner emissions; So its use in fuel has benefits for air quality. NOx, CO, HC and particulates are reduced by up to 30% which is great for reducing SMOG. Ethanol has a high Octane value (109 RON) but a low Energy value.
Is ethanol an aggressive compound?
Unfortunately, these Ethanol & Oxygenator additions to Petrol are chemically aggressive and have a tendancy to infiltrate and attack the Rubber compounds historically used to make fuel hosing, 'O' rings and accelerator pump diaphragms.
Is ethanol a high or low octane?
Ethanol has a high Octane value (109 RON) but a low Energy value. This makes it compatible with classic Petrol but means you have to chuck more fuel in for the same effect. You can increase compression ratio (CR) a little to help offset the loss in MPG due to the higer Octane rating of Ethanol.
Is R12 better than R10?
Though the gradings are not entirely linear; R12 is not necessarily better than an R10 grade as the two hose standards cover different application zones.
