Question 300tdi turbo pressure line plumbing

Hey Everyone,

Been a bit of a lurker here for some time and now find myself with a question I haven't been able to figure out.

I recently picked up a RHD 1997 Wolf 90 with the 300tdi and was looking to put in a boost gauge - my original plan was just to tee it off of the charge pressure line running to the fuel injection pump, when I was following that back I found that there was a tee just prior to the fuel injection pump that also ran to (from my cursory glance) looks like the timing cover and connects to a banjo bolt. I haven't been able to find anything in my parts manual or workshop manual relating to this - any ideas?



Unrelated question, is there ever anyone looking for military radio mounting bits? I have a bunch I pulled out that I have no interest in (pic below).



Cheers,

Blake.

I connected onto the intake manifold. There is a plug there that can be removed.
The treading of that "hole" can be found from a board member here, named "Broncoducer"
PM him or look through his threads.
He recently did one on his 300Tdi.

Yep, most people connect directly to the manifold. It is a better place to measure.

If you are looking for any local help ask over on the local forums. Alberta Land Rover Enthusiasts Club Forum - Index

The manifold thread is m12-1.5.
I bought this off amazon: http://www.amazon.com/gp/product/B001DKM4PU/
I am running an edge CTS for all the gauges and rear view camera.

Thanks for that great timing just looking at installing my McNally EGT/Boost guage and that looks much easier than tapping my manifold.ordered the same kit today!

Cheers,

Brian

Thanks guys, I never noticed that blanked port either. Any one figure out what that last tee by the fuel injector runs to?

Well I did the timing belt this weekend which required taking off the banjo bolt fed by the pressure line from the turbo, turns out it just has a 0.020" hole in the banjo bolt - likely to prevent hydraulic hammering or just smooth out the pressure signal to the fuel injector pump.
