    ECU internal hose.

    Not sure I have ever seen it mentioned but what is the recommended hose for replacement between the ECU barb and the map sensor?
    Not that keen on regular silcone hose as the small bore stuff is usually not rated for pressure unless I am mistaken.

        Yep!
        Looks like its 6mm OD but was concerned about its material. Had a quick look at other external hoses and PVC and EPDM seem to be mentioned. There appears to be no marking on the stock hose that I can see.
        It is just black, smooth and dull so I am leaning towards EPDM.
