Help: Vios Gauge Meter

[teckham23]

Hi bros,

I have a few questions here.

Last week i re-installed my Vacuum Gauge from my old car (Iswara 1.3) to my Vios '05.

Due to the Vacuum hose is too big in diameter (8mm) for the T-joint (to the sensor), I changed the hose to a small diameter (7mm).

Question is:

1.) will it affect the engine if i change the hose diameter to a smaller size?
2.) the mechanic said that Vios is not advisable to intall a Vacuum Gauge as it need sufficient air. Is this true? I have not come across anyone mentioning this.

Thanks & Regards,
Teck
