Evil Energy has great fittings at a great cost.
I have a 600 microprint and used Evil Energy fittings to replace my rubber fuel system with PTFE. Evil Energy products were about half the price of my chassis manufacturer's stuff and they look just as good and haven't leaked for me yet. I'd highly recommend Evil Energy products for the price. They have shown to be durable enough to hold up in the microsprint environment running around 60psi fuel pressure. They assemble well, also, with a cheap Amazon AN -6 wrench.

Great value for great parts!
Fittings work perfectly and went together without any issues. I added fuel injection to my ‘62 Falcon with a 347ci engine. Needed to update the tank and fuel lines and add a return line to the tank. Fuel injection has a much higher pressure demand than a carbureted system. 15 psi vs about 120psi. I bought the 😈 evil energy kit and several extra fittings. Worked great! Only had one leak and that was a fitting I hadn’t tightened all the way. Getting ready to order more Evil Energy parts from Amazon for my transmission cooling system and my nitrous oxide lines. Great products!

Surprisingly Good,
Surprisingly good quality. Threads are proper and not loose. Only time will tell as far as longevity. So far so good. A rarity coming out of this region.

I think that these fittings are real good and what I was looking for the only problem I have is when you first buy some fittings that come with the fuel line or what ever you are using it for I have a problem with it because it does not come with any of these type of fittings so then you have to order more so you get what you want so for that reason I give it a 4 and I hope they start putting these in with the fuel line
