Nope, just off the rack brake tubing from the local parts store. Been working great for 40+ years.

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.

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...

I used rubber coated clamps. I used the factory holes where factory clamps were.

Scott,
Attached are the photos of the 6AN Swedgelock fittings you requested.

Where do we get Swedgelock fittings to use without flaring and attach AN fittings?

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

Most hydraulic shops have the high pressure compression fittings for -6 lines. I think they call them JIC.

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

Go to Swedgelock.com. The manufacturer sells them direct.

Good Morning All,

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.
