    6AN Fuel line PTFE

    I called Summit and ordered 4 fittings a fuel filter and 40 feet of Line 400.00 dollars. Checked Amazon 8 fittings and 20 feet for 55 dollars so I ordered it just to see what’s the difference it’s made in China any body ever used it fitting from Summit was about 20.00 each I could order another and have 12 extra fittings for 110.00 bucks

    I prefer to run steel lines.

    Re: 6AN Fuel line PTFE

    I agree on long sections of line I prefer steel or aluminum.  I will say that Summit doesn't typically make their own stuff, so any fitting, hose, etc. is probably made by someone else.  I've used their fittings before and never had an issue.  Maybe not quite as nice as fittings from Earl's or Aeroquip, but good enough.

    The Summit stuff is most likely made in China as well, they rebrand a LOT of things. On the fittings just be careful that they seat and seal, so do a good pressure test. Other than that I wouldn't worry too much. Also you might have a look through Holley's clearance area, I've picked up fittings for super cheap before, but beware there's a lot to look through. https://www.holley.com/products/clearance_parts/

    Summit Racing is offering Summit Bucks on Russell fittings. That amounts to 25% off future purchases. I bought most of my fittings pre Covid, so the prices were pretty reasonable back then.

    I ran solid lines under the car for Supply and Return and transitioned to PTFE stainless braided lines to the tank and to the EFI.

    Re: 6AN Fuel line PTFE

    In the past, I have used Summit AN fittings for fuel and PS hydraulic SS hose and had no issues with them.
    Recently, I bought several AN fittings, and a fuel filter, from Amazon ("Evil Energy") for an EFI setup (60psi fuel pressure) and did not have any issues with these fittings either.
