fuel filter help

I have a '84 s10 blazer. I was in the process of trying to change my fuel filter. Disconnected fuel lines, etc. My Haynes manual said that there is a clamp holding the filter on, but there wasn't one. It was a cylinder that looked like you could unscrew it or pull it apart at the middle, however I didn't have any luck with that. the side of the cylinder that does not connect to the gas lines bolts directly into the bottom of the engine block,(drivers side). I thought it might be the fuel pump, but I cannot find the fuel filter anywhere else, (it was where the manual said it would be, but I cannot get it apart to see if the fuel filter is inside...

any suggestions??

The fuel filtre should be inside of the driver's side frame.

on the older tbi's is just to the back of the throttle body on the input fuel line
