Review on 🚗 Wisamic Non-dismantle Fuel Injector Cleaner Kit: Premium Tester for Petrol EFI Throttle Cars, 750ML Tank, 145PSI - Complete with Case by Gerardo Goodson

I don't know what the other reviews are about, but this thing does what it says on the tin. The canister is strong and holds pressure well, there is a pressure relief valve at the top of the lid and a shut off valve at the bottom. There are LOTS of adapters available as well as bare hose ends so you can just use the banjo/spike/whatever your motor has. I used this to test and clean a car and it worked great on the first try. Simply order an air supply coupler that fits your setup and (it goes without saying) you'll need to isolate the regulator to remove the coupler from it. It's glued, but with the regulator in a vise, it's immediately unscrewed.
