The fuel filter is integrated with the fuel pump module, located inside the fuel tank. It is not serviceable. The filter itself is also typically not subject to a high rate of failure, so before attempting to replace the module, it would be wise to be certain of the necessity of doing so.
To replace the filter requires replacement of the entire fuel pump module, neither easy, nor cheap. To replace the module, either the fuel tank must be removed from the vehicle, or the truck box must be removed. Either method entails about the same amount of time (a few hours for an experienced DIY'er with the correct tools), but removing the box will likely require replacement of its fastening bolts, since many will probably be broken or rendered otherwise unusable during removal. If removing the tank, try to have as little fuel in the tank as possible, and ensure that the entire vehicle is raised at least 6 inches (have all 4 wheels on ramps, for instance), since the tank will not slide out from underneath without extra clearance.

You can't. Dodge Dakotas use an integrated fuel pump/filter/level-sending-unit module located inside the fuel tank. To change the filter, you must replace the entire fuel pump module which requires either removal of the truck boxbed or the fuel tank.
