after hitting problems with the wiring i finally got round to connecting the boost hose today, i have t'eed off of the FPR but im not getting a reading at all?
if i disconnect the hose from the back of the gauge i am getting a 'suck' effect rather than a 'blow'
(probably not the best words to describe this but most accurate !)
can anyone confirm if this is right?
It is a stack mechanical gauge and the thing that is worrying me is that i took it to bits to paint the back of the dial red and i fear ive probably fooked it in the process!
Any ideas chaps?
