Navara D21 Air Intake

[PrincessJamJam]

Just picked myself up a Navara D21 as my first owned car (previously driving a parents car).

Paid off 100% and feeling good about it.

Runs a dream, has LPG and Petrol, but the EGR is pretty much f##ked.
I'm looking to strip it all out, add in an open element filter and new exhaust system to allow the LPG to breathe better.

I've had a look at the connections to the stock intake and there are 3 larger hoses (2 of which i believe to be the rocker cover breather and a line from the heater tap (?), and the third is a flexible exhaust hose heading into the exhaust manifold)
Also, a smaller line that sits at the bottom right hand side and pulls a very tight U-turn into another engine section.

What needs to be connected to the new air element, and what can be blocked off/bypassed?

I can post pictures as required, just not 100% on what you may/may not need to know.

Thanks heaps in advance for any help! apprecaited!

I've highlighted the hoses i'm unsure of in red.
It was suggested that i put the hose from the first picture into a T-piece adapter along with the breather from the manifold and run that into the air filter.




EDIT: posted same picture twice xD
