It works good！
Works just as it should and good quality fittings
All of the components that come with the kit that I received were top notch quality. The finish on all of the fittings is consistent and the PTFE line was solid. My only complaint was one of the necessary fittings was missing from my kit. I reached out to evil energy and they were quick to respond back to me with a solution. They were out of stock of the specific fitting I was needing, but they sent it my way as soon as they got it in stock. Other than a slight delay, I don’t have many complaints. Would recommend and will be buying more
I upgraded to ptfe line to run e85 bought the ls swap kit and 10 micron filter. Almost a dozen fittings everything went together perfectly and no keaks on start up. Very happy would buy again no question.
Evil Energy has the best fuel systems ever I recommend them to some of my Chevy Riding Boyz giving them five stars ⭐️⭐️⭐️⭐️⭐️
Exactly what my now 16 year old son needed to finish his new top dragster build. Already had the -10 line and fittings.
I used some nylon spacers and riv nuts to attach this to my inner apron. As long as this doesn't leak when filled, I see no problems. This should do its job just fine. To be safe I used some teflon tape on the threads. I've used all evil energy fittings, lines, and hoses on this build. Mostly purchased from amazon, prime shipping is a game changer. So far I have not been let down; only impressed. Thanks EE!
Unbelievable price on a quality hose!
Beautifully Made, I like it.
I've got about 90% of my fuel system parts from Evil Energy, and I absolutely recommend them. Everything works great, and the installation is a breeze. Please keep up the good work, Evil Energy! I'll be back for engine and cooling parts soon
I snagged this kit to soup up the fuel system on my old car, haha. Can't wait to see the final results! The quality is consistently great, and the price is awesome. I'll definitely be buying more.😈
Great fuel solution, great price!
Great replacement for my 10 yr old filter, would buy again.
I no longer need that handful of wrenches to work on my race car’s fuel lines. A very nice piece. Thank
You.
Great quality products and customer service will purchase again with confidence.
Ordered some hose and fittings not to long ago and the hose would not fit in the fittings even though it was the same AN but there was a little misunderstanding but they were very good about helping me find the right hose that i need and good at working through the problems and even sent me the hose i need for free and let me keep the other stuff. 10/10 would recommend
Don’t be fooled by other cheap Chinese hose lines. These EVIL fuel lines comp in nice professional packaging and have the hose ends taped off to prevent splaying. I have purchased other 6an hoses before and they were much unnecessarily fatter inside the steel sleeve. The ID bore is also more consistent than cheap Chinese alternatives on Amazon. Buy with confidence from this seller A+++
Easy kit to use as needed.
