VWs use Magneti Marelli Pica injectors.....probably most of the European cars too
We don't know where you are so we can't tell you where the buy them
eBay looked expensive
Do you have auto parts stores? I'd start there
For the bolts, just buy 4 M5x14mm Allen head bolts:wink2: we'll never tell :grin2:

i think head bolts are best solution...
are the screws of the rail made by titan?
i have another question...when i removed the rail, injectors came with it...they are not "really forced" in the throttle body, aren't they?
they are really "forced" in rail, correct me if i said wrong...

now i saw i made a huge mistake!i hope someone will help me, with injectors wiring

i cant find anywhere the oring size. it could be a O-Ring for Fuel Injector (7.52 X 3.53 mm)?
enthon;
You're in Italy, email Magnetti Marelli and ask them about the fuel rail O-rings
MV doesn't list the injector O-rings......any good automotive shop should have them:wink2:

Call or email Magnetti Marelli and they'll probably just send you 2 for free......
Don't make this a big deal:wink2:

I've taken some oring, i'll see if they fit.
Now there is another problem...
injectors wiring for cilinders 3 and 4 (counting from left), maybe i've inverted the wires..how can i check?

@enthon: The wiring is paired. Injectors 1 and 4 have GREY/RED while injectors 2 and 3 have ORANGE/BLACK

still waiting if anyone knows the dimension of internal O-ring inside the rail
My O-ring is at least 11 years old, and distorted, you take your fuel rail apart and measure yours........
Or wait for Magnetti Marelli to answer.......you're lucky you can ask them in Italian.....they wouldn't
answer me, if I asked in English because that's the way Italian businesses are:wink2:
You need an introduzione or they won't talk to you
