on the subject of metric hose...

alright i found a local suplier of metric hose. FPS in sacramento. great prices and it's on hand. only problem is the largest ID is 17mm sothe larger stuff will have to be mail order.

it's sold in meter leangths, here's what i got. $ per meter, i bought anywhere between 2~10meters. the 10meters was the 3.5mm vac hose as it's everywhere on the mondial, kinda like ferrari thought it was going out of style, flippen everywhere.
9mm $8.95
3.5x2mm $4.49
15mm $10.95
7mm $7.65
12mm $11.50
17mm $11.50

it's black rubber with the fabric braiding. those prices are well below list also, so i gather it varies on the amount you're buying.

no affiliation or anything just apssing along the find, it's not easy to find the metric hose. fpsautoparts.com

cheers'

 

one more, they don't deal with anything related directly to ferrari's however if you know the cross reference to the mercedes/porsche or what direct part number they should have it. i needed injectors and they have the mercedes ones which are also used by the 308 series.
