Fire it up and trip the inertia switch.

 

Bluejay- I know its unreal. It was a $12 job for filter and tool.

Glc- Its after the fact, but for future searchers Can you tell me where this is?

 

Behind the passenger side kick panel, in the cab.

 

 

while it may be a good idea to relieve fuel pressure when changing the filter, don't count on that preventing any fuel from spilling.
I've changed many filters in my day and seen some strange things. I've had lines already disconnected and in the process of removing the filter when the fuel suddenly decides to come gushing out of one or both lines. I always have a pan underneath and wear safety glasses. Gasoline in the eyes is not something I want to find out how painful it would be. Good luck, have fun.
ps, check for fuel leaks afterwards with a lighter
