    Does anyone know the fitting size for the fuel hoses that connect from the filter to the fuel rail?

    I would like to make one just to test the fuel pressure…nothing permanent.

    Thanks

    PS..here is a pic from mine on the 512tr.

    I believe the threads are 14mm 1.5 but I am not sure about the center flare.

    I thought Ferrari did a recall update on mine….but both ends use aluminum nuts.

    The hose were supplied by cohline. That's an old fashioned company with paper catalogue. Their UK distributor (Cohpro) is helpfull, quick, courteous and cheap.

    I have no first hand experience on the 328 or 348... You could drop cohpro an email. He will probably advise against the original braided hose as they do not tolerate ethanol, however he can provide alternate cohline references. So better to ask the expert directly.

    Cohline catalogs can be downloaded here : https://www.cohpro.com/cohline-catalogue

    They are actually referred to as inverted flare fittings. And specifically 14x1.5 mm. You can buy various fittings and adapters on eBay. Don't
    bother with auto stores.

    I'm looking for the 180 degree end fittings that attatch to the fuel rails. Orriginal are blue annodised aluminum but I'd rather ss if available. Any sources ?

    I ordered fittings from BelMetric…

    The interior diameter is 6mm on the 512tr.

    I will keep you posted. They should arrive tomorrow

    This is everything you need. I got these from Matt at BelMetric in the USA. I tested the fit and it works.

    The part numbers are in the picture.

    Hi,
    i want a fuel hose for 348 as a spare part to take with me in the car when driving. Only fore safety and to drive back home
    in case of a problem.
    A straight hose is sufficiant.

    But i am not sure if i understand above "14x1.5". Is it really metric for 348: M14x1.5 ?

    There are two different sizes on Ferrari fuel rails. 14 x 1.5 inverted flare and 12 x 1.5 inverted flare.
    You can measure the male part and it will be 14mm or 12mm. Then you will know what you need.
    I believed the rail size is 14mm and the regulator size is 12mm.

    Ferrari Tech,
    ok. I am able to measure it when it is disconnected.
    "14 x 1.5 inverted flare and 12 x 1.5 inverted flare" is ok for me. I order both. These are standard sizes here in Germany.
    Thank you
    Paul
