I need some opinions on this one......

I noticed the other day that my fuel pressure gauge was down to 3lbs. of pressure from the 1/8 mile on. It's a Mallory pump, not sure which model cause of the way it's mounted in the car I can't see a number on it. It was all ready in the car when I got it. This is a "back up" car and I'm not pulling it apart unless I have to, lol.

The only thing I can think of that's causing this is because the gauge is tapped into the fuel line at the carb, not the regulator. At idle, and up to the 1/8, it's at 7lbs. Does this make sense, or could it be another problem?

Also, the car runs fine and pulls the whole way down the track. It doesn't act like it has low pressure, but the gauge is telling me it does.

Thanks in advance for any help!
