I tried to use brake line since a friend of mine had successfully used it on his hot rod. I just couldn't get it to bend in the right places so I went with the braided hose.

I may be in trouble and not aware of it-- I've been changing steel brake line to AN type fittings for years. Cut the line square, clean up any burrs on the inside and outside, throw the B-nut and sleeve on and a 37* flare. (Cheap Summit Racing flaring tool) burnish the flare and go!
No problem doing that: 37-degree single-flare AN connections are used for very high pressure applications throughout the aerospace industry. 3/8" stainless AN fittings are good for 6,900 psi, and 1/4" AN SS fittings have a working pressure rating of 9,600 psi. Far beyond any requirement in an automotive application...
The easiest and safest (especially for F.I. pressures) way to put an AN fitting onto a tube without the expense of the flaring tools is to use a Swedgelock fitting. I have several 6AN Swedgelock fittings left after my build. I'll send you one for $5.00 shipped. PM me.
Scott,
Attached are the photos of the 6AN Swedgelock fittings you requested.
Thanks for that scott, i updated my thread with the info of that Earls fitting. Let me know if that is what works for you in the end.
I ended up installing a EFI fuel pump from a camaro (well actually truck as the camaro pump was too short) This should solve any loss of fuel at hard cornering which you then need to by hollymat for which is $$$. May as well go direct to the EFI upgrade fuel pump assembly. I will update my thread now with the info

You are welcome, but more than that, thank you for all of the excellent information - I have referred to it many times.

no problems. I just need to find a place to mount my filter so if you got any ideas?? I wish someone posted so much detail like i have been. Some people like Mystic Pete have been invaluable, but its hard to find up to date info on here.
Here is the current status of my fuel pump/filter/line setup for my 1973 LS3/TR6060 swap. It all went together pretty well. I will probably secure the line from the tank to the pre-filter a bit better with a tie-wrap or two and may replace the rubber vent hose with a braided line as well. Using the Walbro GSL392BX Inline Fuel Pump, WIX 33737 Fuel Filters and Russell 650133 Fuel Filter as the pre-filter. The key for me was the Earl's AT165006ERL Performance Tube Adapter Fitting to transition from the 3/8 steel stock fuel line to the -6 AN braided hose.
I was about 0-5 trying to make up those braided hose end fittings before getting the Koul Tool, after that I have made 6 with no issues.
