Fuel Injector Cleaning-Non Running Engine

[SHU-DOG]

Just now thought of this.

Since the truck has been sitting for almost a year now. I would assume the fuel injectors have to have a buildup of gunk in them. I did put fuel saver in the tank and ran it before shutter her down.

BUT

Like I said it has been a while.

So thoughts on how to clean them out??

Also best way to empty bad fuel in tank easily?

Thanks SHU
