OK, i am not quite done with getting my truck going (wiring still left), but i finished routing my fuel and trans lines a few months ago and figured i would share how i ran my set up. it seems hard to find a detailed listing, so im going to try and put up the part numbers i have. i know EVERY truck isnt the same, but it should help!

truck is a 67 suburban, donor motor is 5.3 with a 4l60e trans, both from a 2002 tahoe. lets start up front for cooling, because the fittings will vary depending on the radiator. i used AN-6 for everything.

the radiator i am using is a Spectra CU369.

Radiator Fittings
the 2 fittings that screw into the radiator
SUM-220668B
Fitting, Adapter, AN to Inverted Flare, Straight, Aluminum, Black Anodized, -6 AN, 1/2-20 in. Inverted Flare, Each
(Mfr. #: SUM-220668B

These are the fittings that get "crimped" to the an line
RUS-610095
Fitting, Hose End, Full Flow, 45 Degree, -6 AN Hose to Female -6AN, Aluminum, Black, Each
(Mfr. #: 610095)

VPE-21906
Hose End, 90 Degree, -6 AN Female Thread, -6 AN Hose, Aluminum, Black, Each
(Mfr. #: 21906)
-----------------------------------------------

these 2 lines run from the radiator to the trans (i am not using an external trans cooler). off the transmission, you will need these 2 fittings (they come in a pair so only order 1)

ICB-551114
Fittings, Transmission Line Adapters, Aluminum, Natural, -6 AN Male Threads, 1/4 in. NPS Male Threads, TH350, TH400, 700R4, 200-4R, 4L60E, 4L80E, Pair
(Mfr. #: 551114)

For the an line, you will need to "crimp" these 2 fittings (1 for each line) to mate to the trans fittings

RUS-610095
Fitting, Hose End, Full Flow, 45 Degree, -6 AN Hose to Female -6AN, Aluminum, Black, Each
(Mfr. #: 610095)

-----------------------------------------------
For the lines, i went with the Evil Energy from amazon. heres a link and description, this is the same line i also used for the fuel lines

-----------------------------------------------
Now, on to the fuel setup. these fittings will obviously vary on what tank and sending unit you go with, and also if it returnless rail or not (mine is a return rail). i went with the most basic setup i can find that uses an in tank pump and baffled tank.
