TBM, apparently Porsche have declared that no air cooled Porsches are suited to running on E10, that and the market value of air cooled at the time I was thinking of getting back into Porsche ownership caused me to go water cooled, which in some ways I still wonder if I made the right decision, as air cooled more suit my Luddite tendencies.. and all the more so when it seems there are air cooled owners who have no option but to run on E10 and report no obvious issues.. Though obviously that is not in any way proof positive.
From a dull memory I think I read where Ferrari were able to supply plastic floats for some of their carb setups to replace the brass floats, that were perhaps presenting issues where E10 was in use..? Also thought I read somewhere that E10 was to be or perhaps currently is, the only petrol available in the EU..?
I too replaced the engine bay flexy fuel lines on my carb fed +8, with SAE J30 R6 pipe, in the hope of avoiding modern fuel issues. Though having typed that I use only premium fuel in my +8. When Kevin rebuilt the Mog circa Y2K, he used braided flexible fuel line from the tank to the engine bay, and at a time before there was any mention of possible E10 issues... Fortunately I have a plastic in-line fuel filter as standard, within which the filter element is visible and I keep a close eye on, to date no signs of discolouration or debris from the make up of the fuel line...
I suspect that time/mileage covered may well be part of the possible issues for older vehicles using E10...?
And like others I suspect the issues Sven is unfortunately attempting to resolve, seems unlikely to be E10 related...
