Where is Fuel Filter on 1996 Dodge Ram 1500 / 318

Under the truck on driver side

I've looked at the drivers side also, found huge pellet canister, could it be somewhere else?

1996/1997 fuel pump and filter are in the tank. Not an easy job to do. As always the truck manufacturer puts the parts in an inconvenient place to work with. It's under the truck bed near the back side of the driver. There's a cover on the bed that I noticed that reveals the tank and the fuel pump. But like I said, of course, the Manufacturer put a crossbeam right over the fuel pump. So the tank has to be drained and dropped.
