Default vacuum system removal (HELP)

I would like to remove the vacuum system that operates the wiper door & headlights.
Does anyone have a diagram or even the link to an old thread where this might have already been done before.
I just dont want to leave something unplugged or hanging loose.

Thanks

I'm not sure what you're asking. Do you want to take 'it' all off to work on the systems or do you mean to do away with the systems?
Regards,
Alan

Why! Do you want to convert to all electric?
The vac system works fine if you get all the bugs chased down.
Just wondering ?

I remember a previous post about someone changing over to a screw drive of some sort. But I cant find the thread sorry, I think it worked well though.

I reread the post and saw you were looking to remove the whole thing. The previous post was concerning the wiper door. I have heard of people using a later model firebird headlight actuator in place of the vacuum canister. It looks like a pretty straightforward swap I will try to find the post and get it for you.

Spend $50 for a vacuum gauge and a vacuum system diagram and diagnostic pamphlet; plus spend a couple of hours learning about the wiper door and headlight system. Then, fix them yourself for very little time and money. Lots better than 'buggerin' up' your car and spending lots of time and several hundred $$$$ to get it working [at all] with that mod.

Sorry about the confusion.

The wiper door never worked corectly, so I suspect that during the conversion to RHD something went wrong ???

About 20 years ago I removed the wiper door vacuum cannister(plugged the end of the hoses) & replaced it with a headlight motor from a Mazda RX7.

So now I am going to go electric with the headlights as well & what I really wanted to know is which vacuum hoses can I get rid of. Which ones have to be left? Does the vacuum tank connect to anything else or only the wiper door & headlights?

I hope this clears things up.

Cheers

The "vacuum system" operates the headlights, wiper door, emissions controls, and the ventilation system (whether standard or A/C). The vacuum tank is used to help stabilize the level of vacuum, so there aren't lapses in vacuum which would reduce system performance. If you don't need the A/C or ductwork doors to operate or care about the emissions systems, you could remove the entire vacuum system.

Thanks 7T1vette.
Thats the info I needed. No Air, ventilation system was butchered in the conversion, so I am putting in air at the moment. As for the emissions system, I will have to get someone with more experience to look at what is there, if anything.
Sorry for my ignorance, but is emissions system the same as pollution control system? If so then I can tell you there is no pollution control system on the vehicle.

You are correct. Just different terminology. Pollution control systems were installed to reduce hydrocarbon emissions. Sounds like the only thing that requires vacuum on your car is the can on the distributor (and, if you install air conditioning, the vacuum operated diverter doors in the vent ducting.

The vacuum operated diverter doors in the vent ducting are not required as I am puting in my own ducting tubes to the vents at the lower dash panels. There is no original ducting at all. Its not original air, so I am going at it from scratch.

As the temp here doesnt get below 15 degrees Celsius, I have removed the heater box & dont need the vacuum operated vent there.

The distributor is taken care of.

Thanks for you feedback.

I too want to remove ALL...let me repeat that...ALL the vacuum crap. I want to convert to electric.
It's because I plan on replacing the top end of my engine and remove the vacuum and pollution control crap.

I did the same, but I kept one vacuum line to operate the heater control. (I took the AC out. I can count the Minnesota days I'd actually use AC on one hand.)

Both the Hayes and Chilton manuals have vacuum diagrams. Either manual will tell and show you what you need to know.
