[C320-list] Fuel hose feed to injectors

[Dennis Cookson]

Hi Graeme,

Yes, I see that reference - perhaps I’m describing it wrongly?  Here’s a link <https://c320.org/mediagallery/media.php?f=0&sort=0&s=20200812104248502> to a wider shot of the hose in question.  Any help would be much appreciated.

Thanks and regards,
Dennis Cookson
