just an idea, have you checked theres nothing inside the internal hoses.
there transparent and there is nothing obvious in them. I have also removed all the banjos and blown through them both ways and they are fine, stripped out the noid and its also debris free.
Air is getting to the gauge upto 150-200 but there seems to be a lack of pressure getting to the bolt (if any).
Every trigger pull just results in air being dumped out the noid and fack all else
Will (once again) pull it all apart to quadruple check it untill someone pops up with the part I need.
I'm gonna get a new board for the piece of crap and hopefully thats it done!!!
(getting ragged off with it now as you can probz tell
)
Cheers again for all your input chaps.
