2005 Sedona fuel filter

Having major problems with my Sedona fuel system. Among other issues, trying to determine if my particular vehicle has an integrated fuel pump/filter or is it an external canister? Internet research is very confusing and conflicting. Can anyone shed light on this?

This shows a picture where it sits in the fuel tank. Get a loaner fuel pump tester and check the pressure. Pull the vacuum hose on top of the pressure regulator if gas comes out replace. Pumps pressure regulators and filters are available on ebay.
