Review on 💥 EVIL ENERGY Universal 30-70psi Adjustable EFI Fuel Pressure Regulator Bypass Kit with Gauge and Adapter by Ricardo Anderson

FPR I bought for ITB work failed the vacuum test. I bought an FPR EVIL ENERGY with pressure gauge from Revain because the exchange from the UK to Korea was taking too long. But EVIL ENERGY FPR did not pass the vacuum test either. The reason was that the vacuum in the part in the photo was not working. A rubber O-ring was used on the top to prevent vacuum leakage. The quality of the EVIL ENERGY FPR products is very good. However, the product quality control (QC) is a bit disappointing. The top of the pressure control needs improvement.
