General Is this the boost vacuum line/hose

Hi I'm pretty sure it is the vacuum line but not 100% I've put a green sticker round the pipe in the pictures thanks for any reply and help

I want to add a boost gauge by the way

That is indeed A boost/vacuum line.
BUT don't use that one, it's used for the fuel pressure regulator... .. the short of it.. you risk blowing up your engine if the fuel pressure regulator doesn't see the correct boost/vacuum.

Thanks so what line should I use

 

[aurick86]

the thing is... there are really only a few others:
-the brake servo booster.. avoid this as well!!!
-the PCV connection.. this is the one i'd recommend.

Get the biggest tee that will fit in that hose, then reduce from there to your vacuum line.

Or alternatevely, drill and tap another vacuum nipple in the intake manifold... as they do for LPG installs.
