EVIL ENERGY Overflow Tank Coolant Radiator Tank Reservoir Expansion Universal Aluminum

Mike Strasser

I installed it in a v8 swapped ford ranger!

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!

Good customer service

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

EVIL ENERGY 4/6/8/10/12AN CPE Nylon Braided Fuel Hose Line 5-20FT

William

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+++
