Hey 73,
There is the carb filter that is the metal part that screws into the carb, right after the rubber hose with clamp. ( It's what I see from your pics in another post.) That can be unscrewed from the carb. You can see the flats for a wrench , right against the carbs fuel bowl.
Some models had another filter between the fuel pump and the tank. That should be under the vehicle , inside the frame rails. However it may have been removed by the P.O. It was a canister with a replacable element, and many owners saw it as a hassel. Sometimes it was replaced with a universal inline filter.
This is one of those times you will just have to get under there and look. just a heads up that it may not be there at all.
Also, a clogged fuel filter will not cure your leaky carb or flooding problems. But not a bad idea to change anyway.
Good Luck
