Yep, KB header with a polydyn coating after I got a crack where the 4 runners meet. KB fixed for free and "upgraded" my header with their new, more robust, cast collector.
My setup is the Agency Power Parellel fuel line kit, ID top feed conversion kit/rails/injectors, aeromotive FPR, and various Russell fuel fittings.
There is only 1 return line from the agency power dist. block, so only one port is utilized on the FPR, plus the return line back to the tank exiting the bottom of the FPR.
Not sure on what exact fittings were used, I'd have to go back and check my receipts.
I didn't get this exact kit as I already had rails, pretty sure I just emailed them directly and custom orderes my lines.

Yep, SAMCO coolant, breather, vacuum, ancillary.
Roger Clark Motorsport out of the UK. The kits get pricey, but customer support and shipping were top notch.
Also the website has changed since I purchased a couple years ago. Email customer support is good, save for the time change, if you have any questions.
