Review on 🔧 DIY Fuel Injector Nozzle Gasoline Cleaning Tester Repair Tool Kit for Car Flush Cleaner Adapter - FUAN Universal Auto Cleaning Tool Set by Tim Jolivette

I was checking for a small EVAP leak and slipping on my Hyundai. I bought new o-ring sets and decided they could be cleaned while they were out of the manifold. I watched some repair videos on You Tube, watched grown men squeezing applicator straws against a fuel hose, and decided to do it. Contains Bosch and Denso connectors. Do not use full cans of intake cleaner, too much pressure! First, clean the fuel rail and throttle body rail seats to relieve pressure. Use old o-rings when cleaning the injectors. Replace with new o-rings and seats at final installation. I could add momentary switches to the power lines, the knock was fine, but I'd like to mimic the injector's actual action.
