I need help with FP problem!!

[bobtodd]

I have had my car stored over the last sixth months. One of thing frist things I did this spring before starting it up was install a Kirban fuel pressure regulator. Well, I start the car up and the fuel pressure takes forever to get up to where its supposed to be....like it's slowly building up. Also, whenever I rev the car up the fuel pressure gauge needle doesnt move. The gauge basically doesnt move at all when I drive it either. You can see very tiny fluctuations in the needle but nothing big. The guage is an Auto Meter and I just put it on last year. I have no clue what to do. Could something be clogging my fuel up since it had been sitting all winter? I had a half a tank of gas in it through the winter and I added another five gallons of racing fuel in it before I started it up so there is some good gas in it.
The gauge shows that the fuel pressure holds steady after the car is turned off..no leak down.
I changed the fuel filter last summer. Could the fuel pump sock possibly be clogged?
If anyone has had a problem like this please let me know!! I may try putting the stock regulator back on to see if that does anything different. Thanks for the help!
