IIRC, 8mm connecting the 2 fuel rails together *mm from pressure reg to return line and 7mm from fuel rail to injector. (IMG:style_emoticons/default/beerchug.gif) I've had wine tonight and might be prone to error. (IMG:style_emoticons/default/beerchug.gif)

Make sure you do NOT used the braided hose UNLESS you are going for 100% original. Porsche replaced them on the fuel line recall. Use modern fuel line.

We could tell you the size but why don’t you just measure the fuel rail OD yourself?
The fuel rails are 100% accessible to measure without taking anything apart. Attached image(s)

QUOTE(Mark Henry @ Jul 26 2018, 01:14 PM)  5/16" SAE 30R9 FI hose. (IMG:style_emoticons/default/agree.gif) The FI hose is important. It is rated for higher pressure. Standard hose can work but you are taking a gamble. |
