Fuel filter replacement

[Jeremy R King <kingjer@eng.auburn.edu>]

I changed my fuel filter out with no preliminary gymnastics.  You just 
disconnect the thing and pull it off.  A little fuel will run out, but 
it's not at high pressure.  I'm sure there's a valve system involved.  
The thing to remember is after you put the new one back on, you do have 
to prime the lines.  Easy enough, just turn the key on one step shy of 
cranking (all the dash lights will come on) and leave it on for about 30 
seconds.  Then turn it off and crank the car as usual.  No big deal.
