And more specifically - the area where the front to rear line meets the bias valve, the brackets, etc etc.
Very confusing when you have nothing to work with.

Hi guys, Just need to get the placement right for my brake lines. So i'm wanting to see pics of LS engine bays. Yes, its for my Roundy, but i'm using an LS master cylinder (tandem). Thanks. |

Sweet! Exactly what I am after
Now , more of a technical question. Is it crucial that that big ugly thing (proportioning valve?) be placed on the firewall? Can I just run one outlet to the front lines, and then the other outlet to the rear? Is it that simple? Where will I need to run one of these valves? I notice also that on the rear subframe I removed, the front to rear line went through another splitter/proportioning type thing. Quite confusing! It's all new to me!! |

you can use only one of the front outlets on that valve if you like , yes,,, it`s on the same port,,, Edit--> Oh & oibviously you`ll need to bung up the other hole maybe with a bleed nipple
You can fit the valve anywhere you like You`ll probably want to replace the rear "Limiting Valve" with a "T" piece but you don`t "NEED" to,,, it can actually stay there if you like |

Matt, with that big valve up the front, what is its function? Do I really need to run it? |

William if you are running a rear bias valvle then no you dont have to have the front one at all. And Matt, bunging up nipple's will give you mastitis, not a good thing

** watch this space ** PS.. Will I need anything at the rear subframe? IE still using that splitter/bias valve/whatever the hell it was that was fitted originally?? |

willy that valve (is meant to do) does 2 things,,, one it`s meant to act as a limniting valve for the rear brakes & it`s also supposed to shut off one side if it senses un-equal pressure most times they`re just a pain But when they work , they work,,, when they don`t they don`t
you can do away with it "IF" you do 2 things,,, one fit a limit valve of some sort into the rear line (or use really small rear cyls) ,,, & 2 make sure you use the correct tube nuts (fittings) into wherever you set your pipes up,,, the tandum systems use late metric (double flare) short tube nuts & the early systems take imerial / unf (single ball flare) stuff,,, so don`t mix them up,,, in other words don`t try to fit metric into imperaial & vice versa & you ll be ok |

Alright, sweet. Thanks Matt... very helpful. 
Would this work? Do you see any obvious flaws in it? Sorry for the picture - it's all I could knock up at work
