3.4L Swap custom hose/line ?'s

My "goose" is finally getting some new wings in the form of a 3.4 and I'm documenting everything with photos and notes with the intent of sharing all that I've learned at the end. I'm so busy with work & traveling I have trouble finding the time to properly share everything. I will likely put all the pictures but note mainly the things I learned from the process rather than repeat what others already have.

But...here's where I'm at and I need some YT expertise to keep things rolling.

I'm finally at the point of doing all of the plumbing for the 3.4 and when looking at the ORS instructions, there are some items that I'm hoping that someone will be able to point me in the right direction since ORS is now closed.

So, I went through the instructions and marked everything that they "provided" in their kit. So here it goes...

Fuel supply:
-"blue adaptors" for the fuel high pressure hose for 3.4L fuel supply hose
-high pressure fuel hose that goes to the end of the 3.4L fuel supply hose
-1/4" fuel return hose

Power Steering:

-"blue adaptor" with the power steering hose that goes to the high pressure output of the P/S pump
-"blue adaptor" for the ABS actuator
-brass O-ring to be installed in between the "blue adaptor" and ABS actuator
-power steering high pressure hose from pump
-3/8 oil cooler hose from pump to ABS actuator

Clutch hoses:
-clutch hose between engine bracket and original bracket on firewall
-clutch hose brackets (short for Downey headers, long for stock)

ETC:
-conversion heater hoses (qty 4)
-vacuum hoses for 3.4L canister

I think that's it so I'm hoping that someone has pictures of these so that I can match them up or know where I can find them.

Any help or direction is appreciated!

Any suggestions at all??
I searched and found some pictures of the Fuel and PS lines but had no measurements.

What did you guys do that didn't buy the ORS kit? If I only get an answer about the fuel and PS lines, I'm fine with that...

Thanks in advance for any help

I used my 3.0 p/s lines with the 3.4 pump. I used the 3.4 fuel line, but unbolted it from the fuel rail, flipped it over, and bolted back up. The other end mates right up to the 3.0 hard line on the truck.

For the ps line, I cut a 3.4 high pressure line in half, cut the 3.0 line in half, and welded them together. I don't have ABS so I don't know if its quite this simple for ABS systems.

Thanks guys!
TMZ: are you referring to the fuel line from the donor vehicle? I assume that it has the same fittings on both sides? Any thoughts on clearance issues since I'm using headers?
Did you have to modify the 3.0 PS lines?

Cadman: What kind of weld did you do on those PS tubes? I can have someone at my work do really precise small welds I think...

TIG. A co-worker has been doing all of my welding so far.
