Ok good, I guess when you say TQ tube you are referring to the crossover tube?. Since I will be initially pulling out the one injector that I will have tested at Bosch facility after I install the new Bosch solenoid. If it doesn't pass the test the truck will stay parked awaiting new BBI Injectors, but if it passes I will reinstall it to buy me some time before I drop $3000. But when I reinstall that one injectors I'll probably have to install a new copper washer along with O-ring on the injector And on the crossover tube if it's not all corroded?You really do not need the crows foot wrench if you pull the VC riser, that will clear the TQ tube to use a socket on it. A short wrench to hold the TQ tube when tightening the lines is recommended. Judicious use of pry bar will pop injector loose, same with tubes if you don't want to source all the tools. The TQ tube insert is the only needed tool if the tubes are stuck.
