Installed easily with no issues at all. Holds fuel pressure steady and consistent. The adjustment is smooth and precise. No leaks or performance problems so far. Comes with everything needed for installation. Perfect for performance and LS setups. Build quality feels durable and reliable. Works exactly as expected. Great value for the price. Definitely a good upgrade. Would highly recommend it. Review: Would recommend... To qualified tuners - 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! ## Features - [Application] fuel regulator fit for most vehicle's EFI system. - [Medium] bypass fuel pressure regulator compatible with gasoline,E85 and alcohol/ethanol, not compatible with diesel fuel.

While they look nice, they are crap rubber without nylon reinforced walls. The rubber will TEAR easily and blow a line and leak. Use REAL fuel line with nylon reinforcements, not this pretty SS braided crap rubber hose in the kit. Other wise, the regulator works. ## Frequently Bought Together - EVIL ENERGY Fuel Pressure Regulator 6AN EFI Bypass Return Adjustable (30-70PSI) - EVIL ENERGY External Inline Fuel Pump Electric 300LPH High Flow 12V Universal - EVIL ENERGY Inline Fuel Filter 100 Micron with 6AN 8AN 10AN Adapter Universal 50MM Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/219078008-evil-energy-fuel-pressure-regulator-6an-efi-bypass-return-adjustable](https://www.desertcart.kr/products/219078008-evil-energy-fuel-pressure-regulator-6an-efi-bypass-return-adjustable) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-11*
