Yep any auto parts can get one, BUT it will have the wrong sock on it, and the stock sock won't fit the aftermarket sending unit. If going aftermarket you should IMO remove the sock and install a screw on type filter http://leroydiesel.com/Fuel_Delivery.html (scroll down three items)
X2 - no reason to have a screen or filter in the tank - unless you want to drop the tank to clean the filter. Sometimes the crud or bad fuel requires you to drop the tank and replace it or clean it out. But a external filter can limp you along a few days with a problem tank.
