EVIL ENERGY 30-70psi Adjustable EFI Fuel Pressure Regulator Bypass Return Kit Universal with Pressure Gauge and 6AN ORB Adapter Aluminium Black&Red

This unit is a suprisingly good value, I give this thing high marks for the 70ish bucks it cost me, however... Let talk about what this is and isn't. This IS a fairly well engineered (copy?) AFPR, its holds it's setpoint well, it flows a good amount of fuel and it works well in boost. For the average tuner this FPR will at least eliminate a rather annoying variable (stock FPRs). This isn't a high dollar unit, I dont know if I would trust it to regulate over 500hp or 1 bar of boost but your mileage may vary. It is very likely that it will NOT survive exposure to alcohol, don't even bother trying it, buy a high dollar proven alcohol rated AFPR if that is what you are up to. I installed this on the return side of a Ford 300 I6 Turbo with Ford fuel rail to AN adapter fittings, I simply gutted the stock regulator and welded it back together to act as a passthrough to this AFPR. I set the reg to 42 PSI, hooked it up to a vac/boost ref port and sent it. ZERO variation in the tune, VE numbers look way better, proper flow and pressure are now being maintained on both sides of the injector under boost. No leaks, overall happy. Things to note: TAKE IT APART, make sure there are no shavings, rolled orings or a bad seals, don't be a noob and file a bad review because you didn't do your job. this goes for any Chinese aftermarket car part (BOV, WG, etc.). Double check your work, torque all of the fasteners to a standard specification. Be gentile with the provided fittings, they are made from low grade Chinesium, they do work fine. The supplied hose is meh but I used it anyway and it's fine. Be smart, if you dont know what you are doing, talk with someone who does, dont just install this on your car or truck because you think it's cool. If you dont have a reason to install an AFPR then dont, the stock one is going to work better in your application. NO ETHANOL! You didnt read the whole review, STOP!

Good quality and exactly as others sold for higher prices .

Evil energy made a mistake with my personal order and quickly resolved the issue without hassle. This brings me back to them over and over . Thank you for a quality product Evil E

After I figured out that I had a blockage in my old factory original fuel tank, I was able to get this pressure regulator set perfectly. It seems very well made. Came with lots of extras. I did not use the hoses, because I went with braded nylon, and these were too short for where I had to locate tie regulator. It is well sealed and has not leaked. I have been using it for about a month now. Out of all of these aftermarket regulators on the market, Evil Energy seems to be the very best value. With the vacuum port connected, it maintains the correct pressure at all RPM. It is easy to adjust too.

Did not install this yet but quality looks excellent and packaging is great. Was delivered as scheduled with proper updates. The kit includes ample fittings to do the install job.
