This is what I mean about the trumpets, they have a larger bell mouth than the normal ones used on clios which are 88mm wide I think.
I also had a re-think on the fuel pipe rather than having the section of aeroquip hose sleeved and clamped over the original hose, which im sure would of been fine I have fitted a barbed -6 fitting so it is similar to the way the original end was fitted. I think I will try and find a small clip to fit aswell as a back up.
