Anything special to changing a fuel filter on a 1994 Ford E350 diesel?

Where is the filter located? Is the fuel line under pressure? Do I need special tools?|||it depends on the engine.. the older ones ( 7.3 liter direct injection, no turbo)have a screw on fuel with a water separator on it. its easy, unscrew it, change the filter ( dont forget to put the bowl back on the filter) fill it with clean fuel and put it back on. if its a 7.3L indirect injection ( with a turbo, called a Powerstroke diesel) the fuel filter is a cartridge type inside a housing on top of the engine. no special tools, just remember to drain the fuel from the housing. theres a drain cock on the driverside of the housing. fill it a little less than halfwayfull of clean fuel, put the new cartridge in install the cap with a new o ring. Let her rip. it will probably stall or run rough for a second until the fuel system purges the air, though. 1994 was a cross over year and good ole ford used both engines that model year. i work on these engines everyday, i ve got a whole fleet of them. if you need help, email me dieselskidz28@yahoo.com|||on top of the engine and no special tools|||not able to help-just found this and trying to learn how to use answers--sorry|||it is on top of the engine. it looks like an oil filter. you just unscrew the old one, fill the new one with some diesel fuel, and screw it back in place. start the engine and check for leaks.|||Don%26#039;t forget to %26quot;prime%26quot; the fuel system after replacing it.
