need help with a Holley carb

Lance, as far as the fuel pressure is concerned, I don't know if the guage is bad, weak or what. I don't know how accurate it is. It has a Carter M6907 pump on it and it says the range I believe is between 5.5 and 7.5 max. It is less than 3 years old and only has about 3000 miles on it .What do you check the pressure with other than a new guage. It is probably a good idea to get one.
