E10

[P1800Ray]

How does everyone feel about the change to E10 in the UK?

I've read that all hoses need to be changed to J30/R9 and presumably seals would need changing?

Has anyone got feedback from countries where it was adopted earlier?

The cost of super unleaded has increased 10p per litre this week at my local garage.

A copy/paste from the Saab V4 forum.
"Just an update on this: the fuel hose I used was from Halfords (yes, I know...) rated SAEJ30 R6. As soon as I used it in the tank connection the car always smelt of fuel when I got in, but there were no visible leaks. I guessed it must be permeation so I recently replaced it with 'Gates Barricade' (or possibly 'Gates Greenshield'?) hose, to SAE30 R14T1 - sold as being low permeation, and that seems to have got rid of the smell."

So, R14 looks to be the minimum standard for E10.

E10 has been the norm for regular gasoline in most parts of Canada for at least 20 years. It does not present a material issue for most fuel systems. What I find is perhaps a greater issue is the quality of fuel line available. After I finished the resto on my 142E, I went through at least 3 different brands of fuel injection rated fuel line after they all started hardening and developing cracks in the outer jacket along with requiring constant tightening of the fuel line clamps. For the last two years I have been using a Gates SAE 30R14T2 compliant fuel line and so far it has not shown any visible signs of deterioration or leakage.

Gates has a large range of fuel lines that are sold in the Barricade range and if you are searching be aware that the the part # and product # are separate. I believe that all the Barricade hoses have a product number 4219xxxx. The xxxx is specific to the diameter of the hose, the application and how the hose is sold (various reels / clamshells). The application differences include carb/fuel injection (rated pressure), marine and submersible. My hose is actually 42196040 because it is 5/16" fuel injection rated and came off of a 250 ft reel. You can get carb specific fuel line from Gates which has a lower operating pressure. As noted, they have a submersible rated hose. Stay away from that one because it is murderously expensive. Gates also offers a Barricade Greenshield hose which is different than Barricade. The only obvious performance difference that I can find is that Greenshield is rated for E100 as opposed to E85 for plain Barricade.

The effect of E10 is separate from the issue of permeation through the hose which is a more recent requirement to reduce VOCs. The SAE requirements include permeation in the standard and the requirement to meet that standard may be why there is an issue with accelerated deterioration on some products. An interesting feature of some of these permeation resistant hoses is that if you get fuel on the outside jacket (which is a different material than the inside liner) it will become gooey. The submersible rated hoses don't do this which is one of the reasons why they are much more expensive. I have not encountered the goo factor on the outer jacket on my Gates hoses; but, have not had a leak which exposed the outside jacket to fuel.

I have had Cohline hose recommended to me as a durable product. Unfortunately, it is not readily available where I live. So far, the Gates Barricade 4219xxxx product has been the most durable modern fuel line that I have been able t find.

I read that R14 is for lower pressure applications, would that be a problem for a P1800 or Amazon? Apparently the submersible hose doesn’t like under bonnet heat.

30R14T2 is about the best you can get. 225 PSI Rating and burst pressure about 3 times that. Not sure why submersible hose comes into this discussion, as Amazon and 1800 don’t need that, and it’s typically submersed in the fuel tank, not used under hood.

these seem to have a good range and reasonable prices

I don't kniow why it is but most people seem to only be focused on the correct pipes. This is only half of the "trouble"...

...I feel compelled to carry on with my battle of spreading the word about using ethanol in fuel for engines that are used infrequently.

If you are using a vehicle regularly then the separation of fuel / ingress of water is less of an issue in a fuel system. BUT for machines such as say garden equipment, motor cycles, mobile homes and classic cars folks need to be wary of not using fuel stabilisers. E5 was bad enough - E10 is double the amount!

I've heard stories from the classic motor bike community of folks adding stuff to help get the water content out of the fuel - it is getting to the stage where folks jump through hoops making biodiesel / processing waste vegetable oil (before the fast food industry realised they could make money from this waste product)

Whilst other parts of the world are "more used to E10" I think it is worthwhile encouraging the good folks of this forum who in particular own engines with Bosch continuous injection systems (D-jet) to take sensible precautions to avoid corrosion in thier fuel systems.

Army, initially the OP asked about hoses. There's many a thread about E10 on this forum in the different model sections covering all aspects of ethanol in gasoline. I think the first order of business is to prevent leaking fuel and possible fires, hence the question, and answers on fuel hose.

I agree garden equipment has failed miserably with Ethanol when it was introduced, I lost a mower to that, despite carb rebuild and replacements and other repairs, now someone else cuts my lawn!

Yes, I have a djet equipped 1800, for a few years I was running an E10 high octane (94) fuel. (thats a North American rating). I put Stabil in it every fall. Yes it's anecdotal, but it always started up first try in the spring.

I'm able to buy Non ethanol gas (premium rated 91) here in Canada, so thats what I now run. and use Stabil every fall before its put away. I have the 30R14T2 hose installed.

p.s. not sure what your reference to bio-diesel has to do with Ethanol fuels in our classics.

p.p.s. hope you're getting close to finishing the garage.

c1800, thanks for that - I wasn't aware of STA-Bil - it certainly looks worth a try.
