Re: Stock Vacuum Line Question

that *was* the 'splitter' (it's broken) ... the smaller plastic line woul've connected to this ..

that's what you'll be replacing with the vacuum block - essentially a 1 -> 4 'manifold' ..

Thank you. I have read 100s of post although I just can't seem to find a good pic for dummies for the T1 2.5.

Screw it...going to manifold now. This is a mess.

Easy, 1 line goes to the FPR with a T in it to feed the Baro/Map solenoid. The other goes to the boost gauge with a T in it to run the BOV in the airbox. Take the check valve out of the BOV line as it'll allow more boost to be ran before the BOV "leaks"

Back trace from the end components to the Manifold to see what you're missing.

Post with pictures and explanations with links on where to get new lines. A 5/32 drill by hand will pull the old lines out of the splitter you have pictured and you can install new nylon or polyurethane lines.

Re: Stock Vacuum Line Question

First, thank you so much. I have made the jump to go with the manifold so that's where we are at.

Re: Stock Vacuum Line Question

If you need any assistance Please let us know.

You will have to reuse any orifices or check valves that are in the original system.

Re: Stock Vacuum Line Question

Sir, regarding the purge solenoid and the two line going to the throttle body. Do I run both those lines to the manifold block? I want to keep the evap canister in place.

Thank you,

Re: Stock Vacuum Line Question

The only lines that come from the vacuum block are to the...

1)Baro Solenoid
2)Fuel Pressure Regulator
3)Wastegate Solenoid (Appears to Tee and also run to the Wastegate and Turbo Housing)
4)Purge Solenoid
5)Boost Gauge
(See the attached vacuum diagram)

All other lines will be run as the factory had them as shown in the vacuum diagram.

Okay, wastegate solenoid attaches as noted. So, leave tee in place and run directly to the manifold block for the wastegate and turbo? Cap the wastegate solenoid?

Re: Stock Vacuum Line Question

I apologize for all the questions....I just cannot see it. In the stock config, how does the wastegate and turbo get vacuum from the solenoid. It's just a switch right?
