What size ? - MFI cold start enrichment fuel lines
anyone know what size the MFI cold start enrichment fuel lines are that are located on the plastics stacks ( the lines connect the small plastic T fittings) ?. Think there are 1972 onwards

Internal diameter seems to be exactly a quarter of an inch.
I have one on my lawn mower Petrol feed as it seemed to be a perfect diameter so now I have a Porsche lawn mower.

Notes from the last time I bought some of the small diameter cold start hose (for my '73 911E/S) indicate that it was 4.5mm ID/9.5mm OD & I used ~ 500mm.

I don't think the original plastic ones have been available for years - the only version I've seen recently have been the brass ones.
Unfortunately they're ~ £300 a set ...

theyre not identified on PET .. they go between items 26 and slip into the plastic intake stacks ( 26 = fuel pipe , 27 = clamps )
consist of 2 'T piece' and 1 90 deg per intake stack. Al have a closed end with pin prick sized hole to inject fuel through
mine are ok, just one of them has is out of round
