Holds steady pressure, no leaks.
I installed this in a Jeep Cherokee I plumbed a fuel cell to. Running exclusively evil energy just to give them a shot and stay in the same ecosystem. This will be moved in a few months as I redesign the suspension but for now, it’s working great where photographed. Holds 50 PSI at the rail at idle and WOT. This is a “dead head” design. So simple with the return out of the regulator.I didn’t use the gauge that came with the regulator since I’m measuring at the rail. It did leak horribly where the gauge would plug in and then I read the directions… thread sealant required. No further issues.The directions say not to plug the vacuum port if it isn’t used. That’s a little disappointing as mine will always live under the body. I’ll run a line at some point to the original fuel door. As there isn’t a vacuum, it being opened shouldn’t matter, but I don’t want water to collect in there.

Reviewed in the United States on September 3, 2023
I normally buy from Holley , Aeronotive
decided to try the evil energy brand.
Some of best packaging I’ve seen. The fuel pressure regulator itself , feels incredibly well built. Comes with everything you need even thread sealant.
I have not installed it yet , definitely a good deal
