EVIL ENERGY 6AN PTFE Fuel Line Kit,E85 Nylon Braided Fuel Hose 20FT AN6 PTFE Fuel Line Hose(5/16 Inch ID)

Great kit, best price on the market. Construction of everything looks good. Used it to make my fuel lines. No leaks , easy to maneuver given the thickness too.

So straight up, I'm a parts snob. I usually only use name brand fittings and hose because nothing is worse than having a failure and potentially starting a fire or damaging expensive components in attempt to save a few bucks. I've bought a few Evil Energy adapters before out of Amazon Prime convenience and was always pleasantly surprised by the fit and finish. I bought their 6an PTFE fuel line kit to plumb us an engine test stand thinking it would be fine to build with cheap fittings since they'll all be visible and easily accessible. I'm pretty blown away with the quality so far. No leaks, the fittings are all tight around the swivels (some people have poor tolerances and leaks here), and the assembly process feels comparable to that of name brand hoses and fittings. The only thing I've noticed is that the surface finish and cleanliness of the ferrules is noticeably worse than that of the name brand counterparts. I had to hit a couple of them with a red scotchbrite to clean them up. They sealed up fine though. The hose itself is also surprisingly nice. It looks and feels identical to some name brand hose that I believe is also manufactured in China. I'd bet they're made in the same factory or to the same exact spec. Would I plumb a customer car with this stuff? Definitely not, wouldn't want to risk it. But if I was still building cars in my driveway on a tight budget I would be tempted to go with a kit like this. If you can, pressure and leak test your lines before installing especially if they're for fuel or oil, but for under $100 these kits are a great value. Pictures show a -8an Vibrant fitting and ferrule next to -6an EE fitting and ferrule.

If you are slightly mechanically inclined to a very seasoned veteran like myself, this is a MUST! IAG wants $600 after tax and shipping for their plug n play kit and I built my fuel system on my built 2016 STI for a fraction of the cost. There is some added time and labor to building PTFE over other styles of AN lines but well worth it! ZERO issues with quality and I have way more line than I ever could have needed for my fuel system upgrade and ran perfectly with my Radium Fuel Rails! Just needed to get 10ORB to 6AN fittings to connect lines as well as 6AN Y fitting for fuel feed. I bought a second fuel one kit to also run lines from my Radium Hanger to the front of the car and had enough for the fuel filter and plenty to spare!

This is honestly a great product. I have purchased multiple sets of this brand to finish my LS swapped jeep and have used it for fuel and transmission lines

Quick delivery, packaged as shown on site. easy to install and works as expected.

Quality is better than most other bands being sold on Amazon.

Very nice fuel line and fittings setup! LS swap!

Everything looks good EXCEPT they sent 8an with my -10 hose kit…
