Review on 🔧 MR CARTOOL N20/N55 Automotive Fuel Injector Tool Kit: Easy Installation & Removal for Engine Timing by Redfish Rosenhoover

There is no instruction how to use this tool but given the price it is understandable but you had better learn how to use this tool before tackling it. Someone who misuses this tool can become very costly as you can damage your car engine or damage high pressure fuel injectors. The procedure for removing injectors is different from installing a tool and vice versa. It took me about an hour to figure out how to use it properly every time on the fly and you install the tool very evenly before installing or removing nozzles. The tool may not be fully tightened so first make sure you tighten everything first before using the tool or you could either injure yourself, damage your machine, break the tool or all of the above. This tool and others like it are not for the faint of heart, but they work if used properly.
