    You're right. However it's still rare to fine R9 hose in most parts stores and finding R10 is basically impossible.

    I'd like to think that yeah for hydraulic hoses, 300psi would be low pressure yes.

    Most BMW motorcycle dealers stock bmw fuel hose in 1 meter lengths. It is Really good fuel hose, Iíve used it on everything for the last 15 years or so.

    This. There are a couple small outfits, near me, that do "import" parts (meaning mostly air cooled VW). However, they do carry quality parts for these old cars, and usually stock stuff, like quality metric fuel hose, by the roll.

    I would suggest that the OP goes and finds a store like that, rather than going to the national junk chains (O'Reilly, AZ, et al).

    Please post your topics in the correct forum. General Discussion is not a catch-all bucket for technical questions. Please do not ask questions there.

    If you don't know where to ask your question, post it in General Technical and we'll move it to the appropriate subforum if necessary. Thanks in advance.

    In a pinch I go to CarQuest. I look to make sure it says FI hose on the it before I buy any. They usually have some on a spool.

    Are we just talking about standard rubber efi hose? nothing special on the ends?

    Id just go to any parts shop, they should have it on a roll and you buy it by the metre?

    Go to FCP Euro or AutohausAZ, or another decent online retailer, put in your car info, order the quantity of bulk hose that you need.

    Generally ignore auto parts stores for your BMW, as they won't often have what you need in terms of parts.

    The upper picture says not to use for gasoline.


    You want fuel injection hose with SAE30R9 rating.
