its moulded into the vacuum hose

[Edgeauto]

^^^ feel the hose there will be a hard section which is the check valve

[rnbguy]

nice one lol i threw em out lol, now i gotta get a new hose with the check valve in it -)

what happens running turbo setup without check valve?

[ECU-MAN]

you put positive pressure into the booster instead of vacuum resulting in loss of assistance

[rnbguy]

in english, weaker brakes :P

[ECU-MAN]

iv never tried it, but the way the booster operated probably no brakes.

[rnbguy]

well thats a scary thought, ill go get one
