Also if you want to clean the injectors get a 10ml syringe with plunger removed get a red spray straw and wrap one end with electrical tape, thread straw from the inside, insert injectors into back of syringe, attach red straw to can of compressed carb cleaner, find an old unwanted 12v power supply an attach to injectors terminals using alligator clips, plug power supply into a power strip with an on off switch, pressurize the system by pressing down on the can, turn power supply on and off while adding more cleaner, flip injectors over and repeat on both sides of all injectors. Note you will need new o rings and may have to cut. The old o rings to get a good seal on injectors.
