AN fittings and hose info

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.

Fuel Tank
Spectra GM15C 25 gallon tank (87 blazer/suburban tank)

Sending unit
Dorman 692-056 Fuel Tank Sending Unit Compatible with Select Chevrolet / GMC Models

https://www.amazon.com/dp/B000CGGKU6...YWWJBCKYM41TQ3

Fuel Pump
GM Genuine Parts EP381 Electric Fuel Pump Kit with Seals, Clamp, and Baffle

https://www.amazon.com/dp/B000C9SHOU...E2QYKNMJQ6487Z

Fuel Filter

I chose to go with the stock filter from the local auto parts store.

Wix Fuel Filter Part # 33481

And the clamp i used, which was a little big but it worked
