Vacuum Hoses

Hey Guys

 

What Vacuum Hoses/Outlets do I really need on a Crossflow? For mine, all I REALLY need is:

- idle speed controller

- Brake Booster

- Fuel Regulator

- Inside Air Controller

 

So can I whittle down the Vacuum Outputs to these only and blank off all the others?

For an EFI - all of them.

and

For a Carby running the stock 34adm - also all of them.

 

Normally, they all work together as one happy family.

 

I'm not familiar with the EFI hoses,

but the carby ones relate to timing advance, throttle nudger on over-run,

idle up/timing advance when Aircon is running,

and other similar functions to prevent stalling.

Ah damnit. It’s just so messy!

Sadly they weren't just put there intentionally to look messy, funnily enough they all have a function 

 

You can start blocking things off (as someone did on my XD) but then things stop working! I can't think of any that I'd recommend removing. But I would recommend referring to a factory workshop manual or diagram to make sure everything's where it should be and then some clever routing and some cable ties or conduit can make things look a lot tidier.
