VT Ecotec vacuum hose problem

[darcycammo]

Hi guys long time since i have been on here but i have a problem

Tonight i was playing around under the dash on the LH side and i found a vacuum hose not connected to anything which is sucking in air while the engine is running i traced it back through the firewall to the fuel pressure reg into a T piece

Does anyone have an idea where it should be connected under the dash that would be a great help

Vent selection for heater / air con selector works off vacuum so I'd start there
Go to no.12

If all the functions for ur heater and a/c r working, and it turns out not to be for them, then maybe a previous owner had a vacuum gauge hooked up that they just took out without plugging the vac hose?
