Hey folks,
 
So after getting everything setup on my FC for my fuel system and my regulator in i changed all the vacuum pipes and have the car ready to try start but when i turn it over there doesnt seem to be any fuel pressure, the gauge isnt moving whatsoever, this is the first time i have went this far with a fuel setup so there is the high possibily i have done something wrong lol
 
i have a walbro 255 in tank and a bosch 044 externally
 
here is my setup
 
any help or advise is greatly needed :)

I think we had issues with my FPR when the top wasn\'t air tight, I fitted a small O ring just below the locking nut (missing on the top of yours) and that seems to sort it, otherwise its got no vacuum going to it as its got an air leak.

Should still see some pressure though.

I can\'t quite see on the engine picture but the plumbing in and out of the injectors looks wrong.

If you are sure its plumbed ok I feel maybe you best way forward is to carefully undo unions to find where fuel is and is not bearing in mind the fuel will spray out.  

hope this helps
All the best Clive

after some messing about its been sorted, turns out the connections on the bosch pump were the wrong way round, so have her up and running now but the only problem i have now is that there doesnt seem to be any oil pressure :-s no oil coming out of the front iron to the turbo at all :(
 
and my fuel rails look different as its a parrallel setup and im also adding in a third rail for more fuel to my extra injectors
