| Hello Melle,|
Basically as a result of suitability, longevity, availability. I did not factor cost as it a safety issue - hence, what price your car.

| How long was your longevity test with E10? I've always used whatever was available from the motor factors or branded stuff (e.g., Gates) if bought online. Everything I've used so far has held up fine for 10-15 years (also with E10 more recently), at which point it would probably not be a bad idea to replace hoses anyway. Not picking on you, just not sure how to tell what fuel line is "best". Very much like oil or tyres, some clearly don't work very well, but other than that I think it comes down to personal preference, marketing, willingness to pay a premium etc. I always tell my students they should make sure things are fit for purpose, rather than "best".|

| Gates, Cohline and Codan, have sunk millions of funds in to designing a fuel hose that would combat the effects of E10 and other harmful chemicals in fuel. |
As fuels have developed at pace with an ethanol percentage, so has the requirement of the pipe that carries it. For ages R6 was suitable and then E5 started to appear, fuel pipe was upgraded accordingly and R9 was the required product to carry this fuel safely.
When E10 was announced it would be arriving in 2021, the above companies got on with their R&D to produce hose that would satisfy the requirements - the rating went to R14.
As the levels of ethanol has increased and the R rating has risen to match it, I have moved along with the latest and most ethanol resilient fuel hose.
Gates Barricade, IMHO, is probably the most advanced hose produced to deal with ethanol - that is because it has been specifically designed to deal with E10.
The compatibility of fuel lines and their resistance to E10 will now be tested in earnest. Hose such as R6 and R9 will struggle over time to keep their integrity; as the 10% ethanol slowly degrades the rubber from the inside. Plenty of hose looks A1 from the outside, but it's what is occurring within the hose that is key.
At the end of the day it is personal choice. For me it is about giving my classics the best possible opportunity to combat ethanol.

| I agree that branded hose specifically designed for E10 is the preferable option when replacing fuel lines, my point was that it's impossible to tell for a layperson which one of the known brands produces the "best" option. I wouldn't lose any sleep over it if Gates Barricade wasn't available and I had to use one of their competitors' offerings. ;) |
NL and other countries have had E10 for a few years already, I've not heard of anyone have any problems with fuel hoses or carb membranes on their V4s so far.
