mine drops to 0 in like .5 seconds and untill Chris posted a way to check the fuel pump i couldnt find it. my pump is letting fuel flow back into the tank as soon as it shuts down 
 
this was from a earlier post of his 
 
To check for a leaking injector, hook up the fuel pressure gauge, and turn the key on. After two seconds, turn it off, and then back on for another two seconds. Keep doing this until the gauge no longer goes up. Shut off the key, and watch the gauge. It should not drop at all for a minute. Does it? What about after 5 minutes? 10 minutes? let me know.  
 
then he posted on which explained to take a old fuel filter cut out the ends insert some rubber line (i used vacum lime pressurerise the system use vise grips on the line to block any fuel returning from the pump) 
 
when i did that my fuel pressure stayed all night , I dont know if thats  a problem with the pump but i know what causes my fuel drop so im happy (I will replace the pump with a even larger one this summer)
