Bob_Rich Posted Wednesday at 16:19 Share Posted Wednesday at 16:19 HI It is some time since I last rebuilt my seven (lotus s3 sprint spec crossflow) The hose I fitted back around 2008 I was wondering if from the marking One can tell if it should be OK for E5 and E10 fuel have attached a shot of the markings on the hose which hopefully describes it well enough to see if it is OK Thanks in advance for any help cheers Bob Link to comment Share on other sites More sharing options...
SM25T Posted Wednesday at 16:39 Share Posted Wednesday at 16:39 You want at least hose marked SAEJ30R9 Link to comment Share on other sites More sharing options...
SM25T Posted Wednesday at 16:43 Share Posted Wednesday at 16:43 If your hose was fitted in 2008, it may have hardened considerably by now. See if you can bend it. Often removing a curved hose and trying to straighten it reveals just how hard and fragile it has become ! Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted Wednesday at 16:49 Share Posted Wednesday at 16:49 Hi Bob, DIN73379E fuel hose is suitable for E10 fuel, assuming integrity is otherwise good. Link to comment Share on other sites More sharing options...
JP Posted Thursday at 06:21 Share Posted Thursday at 06:21 Hopefully your hose is not like mine was when I rebuilt... 20220319_164450.mp4 1 1 Link to comment Share on other sites More sharing options...
7 wonders of the world Posted Thursday at 08:09 Share Posted Thursday at 08:09 R14 hose is the better grade Worth buying a roll of Gates Barricade and splitting between 3 members. Link to comment Share on other sites More sharing options...
Miker7 Posted Thursday at 09:30 Share Posted Thursday at 09:30 you learn something new every day, I thought SAE R9 hose was the 'go to' but the DIN hose has a higher burst pressure. I normally buy this sort of thing from Advanced Fluid Solutions. I've heard (not saying they're true) stories when E10 came out of ebay fuel hose being lower grades that have higher grades printed on them.

Bob_Rich Posted Thursday at 11:40 Author Share Posted Thursday at 11:40 Hi All thanks for all the interesting and informing responses I have only ever put 97 grade fuel in it ( following advise of late Steve Parker who rebuilt the engine for me) and I understand that 97 is E5 The fuel hose seems quite flexible. There are no cracks or or any other suspect bits. A short length of this same hose connects the two 40DCOE's I removed this hose when I had the carbs cleaned by Paul at Chelmsford Weber Services. I have refitted the carbs with this same short length of this and this was quite flexible and showed no signs of deterioration. car all back together now thanks for all the help Bob Link to comment Share on other sites More sharing options...
JP Posted Thursday at 12:34 Share Posted Thursday at 12:34 (edited) I also understand that Esso 99 tends to be E0 (zero) at most fuel stations in UK. They had something about this on their website although I can't find it now... Edited Thursday at 12:35 by JP Link to comment Share on other sites More sharing options...

Having no ESSO stations locally & because of the supermarket fuel change to E10 I now use SHELL V Power 99 E5 . After the switch the car starts from cold better & has a more stable tick over when hot. There is no perceivable performance change. So what does that say about supermarket E5 ?

Skipper555 Posted Friday at 13:11 Share Posted Friday at 13:11 Supermarket fuel is cheaper as it has less of the additives that the branded stuff has. Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted Friday at 14:26 Share Posted Friday at 14:26 There shouldn’t be any issues in starting or smoothness of running of a fuel injected car on E10. E10 become widely used here in Canada about 25 years ago and all petrol since the end of 2022 is now E10. In cold conditions some ethanol is actually beneficial to absorb any free moisture in the fuel to prevent fuel line freezing between the pump and injectors when the temperature is below -20C. We used to buy small bottles of Fuel Line Antifreeze that was basically neat ethanol, to add to a tank of fuel in the winter, but E10 made that unnecessary.
