Needle Valve install

[Mcflurry]

Hi all,

I'm about to install a Dawes and Needle Valve in my CRD. I'm just wondering if the connection from the needle valve to the vacuum pump is via the hard line at the front of the motor? I'm unsure if I should be running new line entirely to the pump or simply remove the existing vacuum line from the boost solenoid and put my new vacuum line straight on to the hard line?

Cheers
Brad

Your vacuum take off is the" hard: steel stand pipe that is located at front of eng near alternator. Use existing vac line (if in good condition) from this stand pipe, leave plastic damper in place (if fitted) and run vac line to the needle valve via the "T" that goes to vac side of Dawes and to the turbo actuator diaphragm. Refer to the Chaz diagram attached (Single Stage TDi Dawes Manual Control System). Remember the Vac solenoid is to be isolated (blocked off)_refer Chaz doc and the poor photo attached (loop back first two ports and for the third just cut it off say 50mm length and put a screw in it(screw not shown).

Have a look at this video from bigguwesty (Kallen) hangs around on the forum here

It is for Tllix install but same principles apply.

Kallen help me out heaps when I started out and thanks goes to him.

Thanks Bidja, so aside from using the steel stand pipe I don't have to do anything else with the vac pump?

I think it's all making sense now, I actually came across Westy's video that you linked last night and the explanation was very helpful.

No mate, vac pump should all be good to go, just connect up your vac line.

Have not had any experience with ECU chips, only remap. What max boost you running and can you run higher boost with chip without limp?
