Hi All, the prongs on my gas filter have snapped off when the engine was in transit.
If anyone has a spare, please PM me! thanks:)
Aarrgghh! more bits needed!
Sorry I missed this.
The gas filter is just like a tee piece really that has 2 manifold pressure take off points. One for the map sensor and the second is a spare just for servicing and checking manifold pressure. I have no idea why it has a filter in it but I dont think that you need it anyway.
You could just addaprt any fiting that will fit the manifold and has a suitably vac line take off on it.

Hey thanks for the info, so does that mean I just need to hook one side up to the map sensor and plug the other port? Ie. it doesn't mater which port goes where as long as one is blocked and the other routes to the map?
I got one from Suzuki nz btw it cost about $50

Unless the engine is idling at 4000RPM there's no way it can be producing positive manifold pressure. Sounds like the mechanic hooked up the boost gauge before the throttle body.
Vacuum leaks will cause high idle, but not what you're describing.

To give a bit more explanation, there are two reasons you can't have positive manifold pressure inside the plenum at idle.
1) The engine simply doesn't produce enough exhaust velocity to spool the turbo.
2) At idle the throttle plate is closed, preventing a lot of air from entering the plenum.
However, if you hook up a boost gauge to the intake before the plenum (wrong) then you might see a tiny bit of positive pressure at idle because the turbo is pushing a bit of air against the closed throttle plate.
