I also updated all the brake lines to Earls about six months ago then fitted hard lines to all the fluid reservoirs. Still have some work on the radiator as I'm still in two minds to keep or ditch the electric water pump.
 

Couple of quick questions etc in regards to your fuel system setup...
- Any particular reason you have a vacuum line on the fuel pressure reg? Apart from the length of the vacumm hose, i wouldn't expect there to be much measurable vacuum in your setup, and not really a need to have the fuel pressure adjusted with a vacuum reference, id consult your intended tuner, and possibly delete the vacuum source.
- what fuel are you intending on running? The first part of this is if your running e85, it is a lot more sensitive to fuel temp than unleaded fuel, so you may want to keep an eye on your fuel temp.

The reason im asking is with running a dead head fuel system with the surge tank, the fuel in the surge tank may get quite hot, and in longer races, you may get close to having issues with mixtures if not in closed loop, or worst case scenario bordering on boiling fuel/vapor lock. If that happens or becomes an issue, you may need to look into running a fuel cooler in the return from the reg to the surge tank.

Forgive my ignorance, what the reason behind this?  Something to do with the amount of fuel flow? or, Is this a returnless deadhead?

I would assume its a raising rate reg, so a boost line, fuel pressure increases as the boost does.
 
Altho that silicone hose is not great with boost, or vac infact, exp over a long distance, i would use reinforced rubber / teflon hose.
 
Would there be much difference, regarding fuel pump heating fuel in a surge tank with a dead headed setup vs running through the fuel rail?
I would have thought passing through the fuel rail on the engine and engine bay would heat it up more before it goes into the surge tank.

No boost anymore

Yeah, its fuel that is getting heated up from your high pressure pump and returned straight into the surge tank. And to answer brendans question at the same time, in a normal setup you have a tube running the length of the vehicle normally from the fuel rail back to the surge tank, which allows cooling.

As for the vacuum reference, particularily if you go to throttle based tuning (which i highly common with itb setups) it is more consistant fueling wise to run a constant pressure. Furthermore, as you dont really have a plenum volume, it will suffer from pulsing if the source is off one runner, and even if you run it off multiple runners into a small manifold, its not great. Its just another place to cause issues that isnt really needed. If you were to run a turbo, this would change.

True. I forget things!

I thought it was odd me questioning Nathan, i was thinking i was missing somthing, and i was. Sorry mate ha ha

He actually is using a bell mouthed runner manifold in a plenum with a single throttle atm Nath. 
 
My Beams went backwards with the vac connected to the aftermarket reg (converted from dead head to full flow) if that adds anything here.

Sorry for the late reply. I have been soaking up the sights and sounds of the Bathurst 12 hr. Finally back to reality.
 
First, I am not a mechanic so I will tend to make some mistakes. Thankyou for the input on the rising rate reg and the vacuum line. I was told by the guy who is the engineer of the engine build to run a rising rate reg. I had one in the car, so I simply fitted it. If the engine tuner says to run it, I will. If he says disconnect, I will do that. I could not find a dash 3 tube so I just run the silicon tube. Still, have to wait till the tuner gets his hands on the car.
I was going to buy some fancy surge tank which has the fuel pump inside of it but decided against it as it would have cost too much so I built the system you now see. This 'all in one' system also has the reg fitted to it so I felt there was no harm to run the pump and reg so close to the surge tank as the system I was looking at, is a tested and proven system.
The intake being fabricated is a tuned length runner (very close to the factory unit) but with a larger plenum to suit the new engine characteristics. I will also be running two throttle bodies instead of two.
 

Ah yes you mentioned the twin throttle body some time ago, sorry.
