do you mean the big white plastic ones if you do it will be easier to break them out and buy new ones as they are about 50p each when i tryed getting mine out they wouldnt budge.
 
i replaced these on mine as they wer leaking fuel past them just take the inlet off and i think it was a 19mm allen key cud be 17mm cnt remember and a breaker bar and they will undo and just be careful nt to cross thread the new ones lol
 
I found the 19mm allen key too small on mine. I ended up buying a box spanner to remove them and a tap to re-thread the manifold just so they all went in nicely.

i doubt the old man has allen keys that size. whats a box spanner? cant say ive heard of one before and can you remember the tap size mate.

thanks for your gents
 
box spanner is your best bet thats how i did mine, couldn't find a an allen key big enough.

i take it your putting new ones in, if not make sure you've got some spares just encase you break one.
 
had a stroke of luck, didnt realise where i worked had a hex machine so they have jus made me a 20mm allen key head for use with a spanner. yeah i shall be replacing with new as 3 out of the 4 had to be broke out.
am i likely to have fault codes when all back together coz i still cant get ma vag com workin?
thanks for helping gents
 
that was a stroke of luck then dude,

if you put everything back as it was then i can't see you getting any fault codes to be honest
