1.9 Mi16 fuel hose diameter

[pp205 17]

Hi all, after a very strong smell of petrol whilst driving I discovered that my top fuel hose has a split and is leaking onto the cam cover. 

What diameter is this hose please?

 

Thanks

The high pressure hoses? Nominally 5/16". However, where it pushes onto the the fuel rail it flares out to 3/8".

That’s great thanks Peter

The fact it flares to 10mm is probably why it split, from having 8mm hose forced on.

 

I change the banjo on the filter one Miles at pugracing has, which then needs an 8-10mm reducer fitting to suit the Mi16 fuel rail

I fit a 3/8" banjo fitting to the filter and run 3/8" hose all the way.
