300 Tdi turbo pipe query

Folks

I'm putting a 300 Tdi into my 110. I got it running tonight, just a quick tick over as it's been sitting on pallet for a number of years...

I've connected everything except I cannot work out where the pipe which runs from the rear of the turbo around the back of the engine towards the injector pump goes?? Someone kindly cut it and I'm baffled...

It obviously provides pressure to something - I suspect the injector pump but I cannot see where the heck it goes... Everything else is connected except this...

Also, it has a Bosch immobiliser on the injector pump but seems to be running albeit not very well. Is been sitting but could this be a confused injector pump. Egr blanking plate installed...

Thanks for reading and your assistance...

which one one goes to air filter one goes to cyclone breather

The large braided one is linking the cyclone breather to the air filter pipe in front of the turbo.

It's the thin breather style pipe which runs front epithet vacuum pipe? Sorry if doesn't explain particularly well... See pics below. The second shows the pipe (dirty thin pipe not leading to anything)

theres a turbo boost feed for diaphran on top of injection pump

I must be blind... I haven't seen anything which would look like it would accept this pipe. Back to it tomorrow. You wouldn't have a pic?

Checked pics of my engine... No banjo on it so I think I missed it. I have spare so ill rig it up tomorrow. Hoping that'll make it run smoother as at idle it's up and down and dying. 6 years since it's run so probably needs a little tlc...

Thanks for your messages, much appreciated...
