Fitting Types: Our kit includes a variety of fittings at 0°, 90°, 45°, and 180° angles, ensuring versatility and flexibility during installation, allowing for custom routing in tight or complex spaces.

Precision Fit and Leak-Free Performance: The combination of the PTFE inner layer and the high-quality aluminum hose ends ensures a precision fit and leak-free connection, even under extreme pressure, providing a safe and reliable fuel system.

Very happy with the look and the install. Takes a bit to figuring out the pieces you need. I wished they sold the stainless steel hose and black fitting in a kit. I hade to buy separately. Getting the parts to fit up wasn’t too bad. Figuring the right adapters was a bit tricky.

EVIL ENERGY Overflow Tank Coolant Radiator Tank Reservoir Expansion Universal Aluminum 1L/2L
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!

TJ

This is insane I have bought many carburetors online before and it's always a hassle, lots of adjustments or a slew of unforeseen problems. Just as the other reviews state the product was delivered next day and everything matched perfectly. I installed it in about 20 minutes, primed it twice and on low idle it fired up on first pull. Literally unreal!
