    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.

    Thanks very much Raemin, I have been looking for these 348 fuel line fittings for ages. Do you have any information regarding the ID of the orriginal ss braided fuel lines ?

    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 ?

    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.
