ok i got some shitty ebay boost gauge, i know it might not be accurate but i'm going to have a go at installing it.
through reading other topics i know the vacuum hose for the stock boost gauge is the safest place for the T piece to be put in.
what i wanted to know before i go cutting the vacuum hose is there any danger to the engine if this vacuum hose falls off other than the stock boost gauge not working from what i read it would suck air on idle i.e. negative vacuum?
also if later down the track when i purchase a better name brand boost gauge could i just remove the vacuum hose on my ebay boost gauge and plug it straight into the brand name boost gauge for it to be working?
thanks for any help, haha i know i'm a noob with cars but just dont want to destroy my baby
