Just a point for anyone wanting to re-locate the fuel filter outside the tank:
Be absolutely positive you use a filter made for fuel injection engines, and not one for a carbureted engine! The reason is that fuel injection filters are made to withstand the high pressure of fuel injection systems, the others are not. If you use the wrong type of filter, you could end up with a filter rupture! If a filter inside the tank ruptured, you would have a stopped engine. Outside the tank, a possible fire.
For me, the fuel filter change was not a big deal, since I did all my own work. Added a few dollars and about 15 minutes additional work when the tank was removed to change the air filter anyway.
