Wow man that is crazy clean, nice as. I'm not much of an engine freak... what is that gauge in the engine bay for?
Yes its a fuel pressure gauge. I am running a new fuel setup with a return line which the car does not have from the factory. So I'm also running an after market fuel pressure regulator which is adjustable so the gauge is to see how much fuel pressure for tuning.

But what is the latest thing you installed with all the wires? and how does it work
The latest thing is a tucked wiring harness. This cleaned up the engine soo much. It is a completely rewired harness to clean up the bay, hide wires, and eliminate un-needed crap like the big conjunction box in the harness.
Ok thanks for that. You said it is for tuning. So do you have another gauge inside to monitor when driving or is it not needed?
Just trying to make sense of a gauge that won't be seen whilst driving.
When tuning your car and especially when you are boosted you need to make sure you can keep solid fuel pressure to the fuel injectors. I currently removed ALL the stock components to the fuel system and am running all new lines, fittings, rails, FPR, injectors, and etc. When tuning in boost you can start seeing fuel pressure drop up high in the RPMs so we use an adjustable fuel pressure regulator to add more or take away fuel. The gauge is to indicate how much pressure we are running. It's also helpful for diagnosis problems in the fuel system for example if a pump is going weak. You'll have less pressure at the injectors. No need to have a fuel pressure gauge inside the car. Big race cars will sometimes have fuel pressure in the car but not needed. Once your fuel pressure has been set you just keep it as a reference.
The biggest need for it is initially setting up a new adjustable fuel pressure regulator. If pressure is to high you have issues, if to low you do too. Stock fuel pressure is around 55psi I believe so with having a gauge while getting my car running I'll be able to adjust the regulator closest to stock to get me going.
One of my internet friends was going through Avid Racings website and saw my engine. He then realize the whole article was mine. He called me up and told me about it and sure enough I scoped it out myself. I'm on their website. It's nothing fancy or anything but it made me feel pretty cool. Like the million DIYs I do and all the help I give pays off in the end sometimes
hey bud nice car and nice mods,,, looking heaps sick aye,,, where you located in the usa, im sinking about moving over to the states end of next year to work
