300ZX Z31 vacuum pump delete. 

Very helpful brother you made this so much easier than I thought it was going to be., Im Having the same problem with air only coming from my defrost vents

Thanks for the video it helped, but i actually installed the pump hahha, i got my z as a shell, i'm just trying to get everything back to stock

Do more z31 delete videos bro!!

can i just block the intake manifold line? i dont care about the ac, im deleting all ac related stuff

That is not a vacuum pump, that is the vacuum canister. There should be a check valve between the between the intake vacuum line and the canister. While under heavy acceleration the intake manifold loses vacuum and can cause the a/c system and cruise control to malfunction. The canister prevents this from happening by holding vacuum. There is nothing to go bad on it besides the solenoid for the water valve. Only turbo models had a vacuum pump.

Huge question I deleted the watercock because I thought no heat no problem but I was mistaken and I reinstalled my watercock but idk if the coolant hose coming from underneath the engine bay goes to the top or bottom hole and I don’t want to mix them up so do you know?

I want to fix my hoses..so are they standard size? What size? thx the video shows me a lot!

Hey, with the heater valve, I want to keep a/c and heat. Do I T the valve into vacuum from the intake? Looks good I just bought an 86t with digital climate.

I have a 1985 Nissan 300ZX my hvac heater core control went out I can’t find a part for it can you please help me

The Vacuum canister is important to operate the Heater and AC if you want to give it to Me Ill Take it

Im trying to delete all emissions thing not needed it sucks
