How do i fit/wire a boost gauge in?

[jake_smith]

Standerd g40 with standerd charger just rebuild by jabba and just a air filter. There the only mod's

The boost gauge i have has 1 red wire (positive?) and one black wire (negative?) and a like clear 4mm hose thats pretty long.

Any idea? thanks guys new to g40's

You connect the hose into the fuel pressure regulator pipe with the t-piece that the kit has.
Red is positive, black is negative...
