My Coupe has been laid up for the pandemic and my interior work, today I went to fill up with E5 which I did however! on the way home I could see the petrol gauge going down and could smell petrol so I stopped only to see petrol leaking badly luckily no where near the exhaust so I hurried home.
I jacked up the car and found the rubber stainless steel covered fuel pipe was leaking at the Facet pump, so I removed the pipe and the rubber had split and was "VERY VERY" soft! This was fuel grade pipe ?? years ago! I have ordered new Ethanol Proof pipe so best to check!
I lost a lot of fuel it could have been a lot worse if the leak had been elsewhere! so please check

There is another weak point in the fuel lines, the very small 'O' ring that seals the fuel reserve changeover thingy. If that degrades it will ollow fuel to pour out under the car. Ethanol proof rings are available from classic Rover suppliers (P6 as well as P5).

I am no longer keen on braided hose as the condition of the rubber cannot be seen. I still have some on the P2 which appear OK so far. I will have a check on the reserve O ring as I have been using E5 most of this year

That was a shock!
Apparently, E5 will remain (in some stations?) when E10 comes in next month.
However the 'premium' unleaded apparently has no ethanol? I only use this, although more expensive than the rest.
Best continue down the 'check and change' route with hoses, I guess.

Very important to remember to disconnect both main & reserve supply lines from the tank BEFORE working on the reserve tap otherwise petrol will syphon out.

E10 regular has replaced E5 around here since the beginning of August. At present I am using it to see what impact it has but so far nothing different

I am told that Esso super unleaded does not have Ethanol, yet.

I will wait and see - unleaded fiasco withdrawal is still arousing panic and despondency 25 years after it surfaced. No real problems ensued for most classic car owners although some spent money that was not required

Ok we know Ethanol E5/E10 has issues for us guys where do you think we may get problems?
My input :-
1 Rubber hoses
2 Fuel Reserve Tap O ring
3 SU Grommets on the Delivery Tube from the Float Chamber (waiting for SU to ring back) They did and they recommend replacing
4 AED Diafragram (I changed mine as the rubber disappeared) new ones are ok with Ethanol
5 Old Brass Floats in Float Chamber (just spoke to Burlen these are a concern)
6 Fuel left in the Tank while storing (without Stabiliser being added)
Operating Classic & Historic Vehicles on E10 Petrol
If you should decide to make the necessary vehicle fuel system modifications together with the addition of an aftermarket additive
to operate your classic or historic vehicle on E10 petrol. The FBHVC strongly recommends that you regularly check the condition of the vehicle fuel system for elastomer and gasket material deterioration and metallic components such as fuel tanks, fuel lines and carburettors for corrosion. Some plastic components such as carburettor floats and fuel filter housings may be become discoloured over time. Plastic carburettor float buoyancy can also be affected by ethanol and carburettors should be checked to ensure that float levels are not adversely affected causing flooding and fuel leaks.
Ethanol is a good solvent and can remove historic fuel system deposits from fuel tanks and lines and it is advisable to check fuel filters regularly after the switch to E10 petrol as they may become blocked or restricted. If your vehicle is to be laid
up for an extended period of time, it is recommended that the E10 petrol be replaced with ethanol free petrol which is available from some fuel suppliers. Do not leave fuel systems dry, as this can result corrosion and the shrinking and cracking of
elastomers and gaskets as they dry out.

On the way back from a holiday in Scotland I was unable to get super unleaded at Warwick services, so I had to fill up with E10.
I had a trip planned for today and am now on my second tank of E10.
I think that she goes better and no pinking.
When I lay her up for the winter I turn the fuel pump off and let her run until the engine stops.
Hopefully I can get some super unleaded before I lay her up at the end of October
During the winter I shall examine the fuel system carefully and replace anything that seems to be deteriorating.

The current fuel 'crisis' doesn't help either.
I've been using Premium for the 4 years I've owned my coupe, and that is E5.
No alternatives available, so we all need to be wary, or as John W says, change everything that's prone to ethanol degradation.

The problem is knowing what damage is, or is not, being done to the components that make up the fuel system and only time will tell on that one.
I remember when leaded fuel was withdrawn and the only fuel available was unleaded. There was the usual doom and gloom in the motoring press and all sorts of aditives were suggested.
I altered my timing from 6 BTDC to 3 BTDC and away she went with no other problems.
The fuel available today, even with Ethanol, is probably better quality than what I was filling up with in the 70s.
Oil is the same, remember Duckhams Q, it does not compare with the classic oils available now.

We must be aware that E5 designation means 'up to 5%', anything from zero to 5. This means that ESSO, for instance, that has no Ethanol, could well be labeled E5. Indeed E10 might actually be 5.5%.

I concur, having checked Esso's website. ''Synergy Supreme +99'' is ethanol free, BUT for certain 'technical supply reasons' sometimes, may contain some! (In certain UK areas.) At least we know and that it is more expensive, surprise surprise!  |

At least we know and that it is more expensive, surprise surprise! Does anyone know if that goes for all the premium petrol brands ? I have to use them on my Audi as they are prone to coking up on my model Not that ethanol will effect that as it is a much newer car |

You can only try researching on the respective company's website.
Assuming they are clear and not misleading!
Good luck!

Still OK so far in all 6 of our classic Rovers + BMC Mini on E10 - the newish Unleaded compat hoses OK so far, as well as the Atco lawnmower! To few miles covered to note any difference in MPG but performance at legal limits is just the same but more water is bound to have some detrimental effect on performance and durability of some components if not used regularly. Unleaded use made no difference and was in fact better than LRP stuff 20 years ago in spite of the doom and gloom that still lingers with it! |

As an ex tanker driver technical supply issues could simply mean the tank could have been carrying E10 before being loaded with E5 without tank being purged.
As an aside, I have replaced my fuel tank float with plastic one, new E10 proof floats in my twin carbs, new E10 fuel line.

I rang SU several weeks ago if you have plastic floats there is no problem the two small rubber seals on the delivery tubes at the base of the float chambers was a concern and they advised changing them. |

Having just used the POR15 fuel treatment in my tank hopefully slowing the corrosive properties of E10, I thought some of you may find this interesting. youtu.be/UvS_D4_lF5UBoz. |

Here you go guys.
Hmm! I'm glad I don't have to use ethanol in my classics.
Why not consider using LPG. It's gentle on engines, the oil stays clean seemingly forever and it also burns clean as a fuel. The smell associated with LPG is an odorant added to the fuel for safety reasons, it's not a pollutant.
The car's original fuel system (complete with the factory SUs) can be retained without damage, as a backup system. Dual ignition kits for both fuel systems are readily available today.

Hi Vince what is the price of LPG in OZ it's now 72p here I run my Honda on it.
I don't know the regulations over there? here it has to be inspected if you do a self install or it has to be done by a certified installer (they charge £100 for DIY inspection), a certificate has to be produced for insurance cover! the car will then be changed to a dual fuel vehicle, cost wise "was"around £800-£1000.
