 | Fuel Pump Hey Guys, I'm looking to clean the injectors for 2007 Denali 1500, LQ9, for the first time. Have a 3M fuel injection cleaning setup and 3M solvent. First anyone have a suggestion for deactivating the fuel pump? Once deactivated, what'st the best way to bleed the pressure off of the system? Finally, are special tools necessary for disconnecting the fuel inlet and return lines from the rails? Thanks! Rick |

 | isnt it just the one that you plug into your brake booster vaccum. if it is you shouldnt need to do anything otnher then unplug the vacuum line and walla. if its not you do need special tools to get the lines diconnected and you could probley jump pull the fuse for the fuel pump but im just kinda guessing on it. you might want to find the owners manual for the 3m cleaner. |
